Tantalum Capacitor Tantalum Capacitor As of Nov. 2004 Tantalum Capacitor ■ INTRODUCTION Tantalum capacitor are designed with excellent performance characteristics for filtering, blocking, and R.C tunning circuits. They are used extensively in industrial, commercial, entertainment and medical electronic equipment. They exhibit the proven characteristics of wide temperature range and long-term stability. The advantages of tantalum capacitor electrolytic capacitor consist of their chemical stability, the low thickness and high dielectric constant of the tantalum oxide layer, and the capability of sintering anodes with a very large surface from tantalum powder. The low reactivity of the tantalum oxide layer allows the employment of highly conductive electrolytes, and thus achieves a low series resistance. Capacitance and dissipation factor in relation to temperature and frequency thus prove to be very favourable. Additionally, there is also the wide temperature range of several types form -55℃ to +125℃. A further advantage of the dielectric being inactive is a leakage current that is smaller than of aluminium electrolytic capacitor which does not rise considerably even at dead storage. Tantalum electrolytic capacitor thus show a very long life during operation and storage. The capacitance of the tantalum electrolytic capacitor is very high due to the high dielectric constant and the low thickness of tantalum oxide layer. The use of sintered anodes with a large surface allows very small dimensions that cannot be reached or exceeded by any other capacitor. The tantalum electrolytic capacitor at issue are polarized capacitors. In the case of polarized electrolytic capacitor, the dielectric is structured in such a manner that the flow of current is interrupted in one direction. It is therefore necessary to observe the indications regarding polarity when using these capacitor(positive pole on anode and negative pole on cathode). In the case of tantalum capacitor, a mispolarizing is permissible up to the values indicated in reversal voltage. The tantalum capacitor is a polar electrolytic capacitor. The anode is a porous body of sintered tantalum powder. A layer of tantalum oxide is formed over the whole sintered anode surface by an electrolytic oxidation process. This oxide layer, which has a high dielectric constant(ε≒27), functions as the dielectric medium of the capacitor. The final thickness of the layer determines the rated working voltage of the capacitor. Manganese dioxide, a solid semiconducting electrolytic, is deposited in the pores and on the external surface of the formed anode to serve as the cathode. Electrical connection to the cathode is effected by applying a metallic coating to the outer MnO2 layer. As a result of the high stability of the oxide layer the leakage current to the capacitor is very small, even after prolonged storage. The use of a solid semiconducting electrolytic guarantees high stability of the electrical properties over long periods of time and over a wide range of temperatures and frequencies. - 1 - Tantalum Capacitor ■ FEATURE AND APPLICATION ● Feature The product is a standard type that has been most widely used among tantalum chip capacitors. - Molded Case available in four case codes. - Compatible with automatic pick and place equipment. - Meets or Exceeds EIA standard 535BAAC . ● Application - General electronic equipment - Smoothing Circuit of DC-DC Converters & Output side of AC-DC Converters - De-Coupling Circuit of High Speed ICs & MPUs - Various Other High Frequency Circuit Applications - 2 - Tantalum Capacitor ■ STRUCTURE - 3 - Tantalum Capacitor ■ APPEARANCE AND DIMENSION L W1 W2 H Z Z DIMENSION (mm) Code EIA Code L W1 W2 H Z 16+0.15 0.85+0.15 0.85+0.15 J 1608 0.6±0.1 0.4±0.1 -0.1 -0.1 -0.1 P 2012 2012 2.0 ±0.2 1.25 ±0.2 0.9 ±0.1 1.2 MAX A 3216 3.2 ±0.2 1.6 ±0.2 1.2 ±0.1 1.6 ±0.2 0.8 ±0.3 B 3528 3.5 ±0.2 2.8 ±0.2 2.2 ±0.1 1.9 ±0.2 0.8 ±0.3 C 6032 6.0 ±0.3 3.2 ±0.3 2.2 ±0.1 2.5 ±0.3 1.3 ±0.3 D 7343 7.3 ±0.3 4.3 ±0.3 2.4 ±0.1 2.8 ±0.3 1.3 ±0.3 E 7343H 7.3 ±0.3 4.3 ±0.3 2.4 ±0.1 4.1 ±0.3 1.3 ±0.3 - 4 - Tantalum Capacitor ■ PART NUMBERING TC SCN 0J 106 M B A R ●1 ●2 ●3 ●4 ●5 ●6 ●7 ●8 ●1 Abbriation of Tantalum Capacitor ●2 Type of Series ●3 Rated Voltage Code ●4 Capacitance Code ●5 Capacitance Tolerance Code ●6 Case size Code ●7 Packing Code ●8 Packing polarity Code ●1 Tantalum Capacitor The symbol shows a simplified character of the tantalum capacitor. ●2 Type of Series Thesymbolshowsthetypeofthecapacitor.(SCN,SCS) - SCN : Samsung Capacitor Normal - Standard series - SVN : Samsung enVironmental capacitor Normal - Pb-free series ●3 Rated Voltage Code Symbol DC Rated Voltage Symbol DC Rated Voltage 0E 2.5 1C 16 0G 4 1D 20 0J 6.3 1E 25 1A 10 1V 35 ●4 Capacitance Code Symbol Capacitance (㎌) Pico Farad (㎊) Symbol Capacitance (㎌) PicoFarad (㎊) 105 1.0 10×105 685 6.8 68×105 106 10.0 10×106 476 47 47×106 107 100.0 10×107 477 470 47×107 ●5 Capacitance tolerance Code Symbol Tolerance(%) Symbol Tolerance(%) K ±10 M ±20 - 5 - Tantalum Capacitor ●6 Case size Code Case EIA Code Case EIA Code J 1608 C 6032 P 2012 D 7343 A 3216 E 7343H B 3528 ●7 Packing Code Symbol Packing Code A 7inch C 13 inch ●8 Packing polarity Code Taping and Taping and Bulk Reel for Chip R Reel for Chip L B Direction Direction of Feed of Feed Tape + Polarity Mark +PolarityMark - 6 - Tantalum Capacitor ■ PACKAGING ● Marking ▶ JCase Mfdvh71:㎌ 916Y + Polarity (White Stripe) S Capacitance & Working voltage Code CAP. 1.0 1.5 2.2 3.3 4.7 6.8 10 Marking (6.3V basis) Code a E J N S W A 【Code Reference】 Y ㎌ 4 6.3 10 16 1.0 a B C 1.5 D E F G 2.2 I J K L 3.3 M N O P 4.7 R S T U 6.8 V W X Y 10 Z A - 7 - Tantalum Capacitor ▶ PCase JA Capacitance Code DC Working Voltage (G:4V J:6.3V A:10V C:16V D:20V) Polarity (White) Capacitance Range 1DIGIT 2 DIGIT <1.0㎌ A Small Letter ASmallLetter 1.0㎌≤ Cap.< 10㎌ A Capital Letter ASmallLetter ≥ 10㎌ A Capital Letter A Capital Letter 【Code Reference】 Y ㎌ 4 6.3 10 16 20 0.22 gj jj aj cj 0.33 0.47 gs js as cs ds 0.68 gw jw aw cw dw 1.0 Ga Ja Aa Ca 1.5 2.2 Gj Jj Aj 3.3 Gn Jn An 4.7 Gs Js As 6.8 Gw Jw 10 GA JA AA 15 22 GJ - 8 - Tantalum Capacitor ▶ ACase A106 Capacitance Code (A:1.0 E:1.5 J:2.2 N:3.3 S:4.7 W:6.8) DC Working Voltage (G:4V J:6.3V A:10V C:16V D:20V) Polarity (White) ▶ BCase 10 Capacitance in ㎌ 20V DC Working Voltage Polarity (White) ▶ C,D,E Case Polarity (White) 10 Capacitance in ㎌ 35V DC Working Voltage - 9 - Tantalum Capacitor ● Embossed Plastic Type Embossed The tantalum chip capacitors shall be packaged Right hand Carrier Orientation available in tape and reel form for effective use. - Tape : Semitransparent embossed plastic - Cover tape : Attached with press, polyester - The tension of removing the cover tape, F=10∼70g Hpervvhg G4 H I D Z E G5 S4 w S3 S5 N W±0.3 F±0.1 E±0.1 PO±0.1 P1±0.1 P2±0.1 D1+0.1 A±0.2 B±0.2 K±0.2 Case (± (± (± (± (± (± (+0.00 D2Min. t (± (± (± Code 0.012) 0.004) 0.004) 0.004) 0.004) 0.004) 4) 0.008) 0.008) 0.008) ø0.6 0.25 0.98 1.80 1.0 J* (0.024) (0.0098) (0.039) (0.071) (0.039) 1.4 2.3 1.4 P* (0.055) (0.091) (0.055) 8 3.5 4 0.2 (0.315) (0.138) (0.157) (0.008) ø1.0 1.9 3.5 1.9 A (0.039) (0.075) (0.138) (0.075) 1.75 2 4 ø1.5 3.3 3.8 2.1 B (0.069) (0.079) (0.157) (0.059) (0.130) (0.150) (0.083) 3.7 6.4 3.0 C (0.146) (0.252) (0.118) 0.3 (0.012) 12 5.5 8 ø1.5 3.3 D (0.472) (0.217) (0.315) (0.059) (0.130) 4.8 7.7 (0.189) (0.303) 4.25 E (0.167) Cover Tape F 15˚ Removal speed 50mm/sec - 10 - Tantalum Capacitor ● Reel Demension D R C N A B G t Tape A±2 C±0.5 D±0.5 B±051 t+0.5 NMin.

  • Introduction What Is a Polymer Capacitor?
    ECAS series (polymer-type aluminum electrolytic capacitor) No. C2T2CPS-063 Introduction If you take a look at the main board of an electronic device such as a personal computer, you’re likely to see some of the six types of capacitors shown below (Fig. 1). Common types of capacitors include tantalum electrolytic capacitors (MnO2 type and polymer type), aluminum electrolytic capacitors (electrolyte can type, polymer can type, and chip type), and MLCC. Figure 1. Main Types of Capacitors What Is a Polymer Capacitor? There are many other types of capacitors, such as film capacitors and niobium capacitors, but here we will describe polymer capacitors, a type of capacitor produced by Murata among others. In both tantalum electrolytic capacitors and aluminum electrolytic capacitors, a polymer capacitor is a type of electrolytic capacitor in which a conductive polymer is used as the cathode. In a polymer-type aluminum electrolytic capacitor, the anode is made of aluminum foil and the cathode is made of a conductive polymer. In a polymer-type tantalum electrolytic capacitor, the anode is made of the metal tantalum and the cathode is made of a conductive polymer. Figure 2 shows an example of this structure. Figure 2. Example of Structure of Conductive Polymer Aluminum Capacitor In conventional electrolytic capacitors, an electrolyte (electrolytic solution) or manganese dioxide (MnO2) was used as the cathode. Using a conductive polymer instead provides many advantages, making it possible to achieve a lower equivalent series resistance (ESR), more stable thermal characteristics, improved safety, and longer service life. As can be seen in Fig. 1, polymer capacitors have lower ESR than conventional electrolytic Copyright © muRata Manufacturing Co., Ltd.

  • Technical Notes for Electrolytic Capacitor
    TECHNICAL NOTES FOR EL ECTROLYTIC CAPACITOR 2. MANUFACTURE OF ALUMINUM ELECTROLYTIC CAPACITOR Raw Aluminum Foil (1) Etching To obtain higher capacitance, surface area of aluminum foil for electrolytic capacitor increases through etching process. In etching process, aluminum foil is applied with DC or Etched Aluminum Foil AC current in a chloride solution to preferentially dissolve the surface. Surface area is increased by 60-150 times for low voltage foils and 10-30 times for high voltage foils. (2) Anodization(Formation of Dielectric Layer) Aluminum foil for electrolytic capacitor is further formed with anodic oxide film (Al2O3) on the surface as dielectric layer. Etched aluminum foil is immersed into a solution Formed Foil including ammonium salt of boric acid or phosphoric acid and applied with DC voltage so that the foil Aluminum Oxide becomes positive and the solution becomes negative. Then aluminum oxide film is formed on the surface in proportion to the applied voltage. The anodic oxide film, having the thickness of 13-15 angstrom/V (1.3-1.5 nm/V), is extremely thin, compact and highly Aluminum Substrate insulating. RUBYCON CORPORATION 2 TECHNICAL NOTES FOR EL ECTROLYTIC CAPACITOR Slitting (3) Slitting Process Etching and Forming are processed with wide roll of master foil. Then the master roll is slitted into individual rolls with specified width as per the specification. Stitching & Winding (4) Stitching and Winding Slit anode and cathode foils after slitting process are stitched with lead tabs and wound into cylindrical element together with spacer paper. Spacer paper is to contain liquid electrolyte that works as real cathode and restores damaged dielectric film, as well as maintaining the distance between anode and cathode foils constant to prevent short circuit.

  • With Flexxon Power Loss Protection Features Dram
    What is Power Loss Protection (PLP)? Need to secure your data against unexpected power shutdowns? Your wait is over - Flexxon’s SSD Power Loss protection offers the best-in-class data security with NEVER LOSE YOUR DATA AGAIN! DRAM-less design, reliable supercapacitors, and standalone tantalum capacitor array that lasts for WITH FLEXXON POWER LOSS decades. PROTECTION FEATURES High-performance data storage devices are available at affordable prices in the market, but with a major drawback. The problem is that they are unable to protect data during power failure. That’s where Flexxon SSDs come to the rescue. During SSD operation, data is temporarily stored in DRAM for improved performance. But DRAM needs an external power supply to function. So, in case of sudden power failure, power to DRAM is cut abruptly and critical data is lost. DRAM-less Design Capacitor provide power to the DRAM during sudden power External DRAM puts in-flight data at risk. failure, making it possible to flush data from DRAM to NAND memory. How Does PLP protect my data? The data is temporarily stored in DRAM for better performance. But DRAM functions on external power, so data can be lost during sudden power failure. Flexxon Supercapacitor Technology Power Loss Protection provides a time window to quickly More efficient than industrial batteries, secure data by flushing it from DRAM to NAND memory. supercapacitors offset risks from power loss. This is achieved because of power loss solutions added that power up the DRAM so that data flushing to NAND is complete. As a result, you no longer have to worry about power losses Tantalum Capacitor Array Protect data in the write cache with capacitors that last for decades.

  • Reliability of Tantalum Capacitors
    NASA Electronic Parts and Packaging Program (NEPP) Reliability of Tantalum Capacitors Effect of Inductance and Requirements for Surge Current Testing of Tantalum Capacitors Alexander Teverovsky QSS Group, Inc. Code 562, NASA GSFC, Greenbelt, MD 20771 [email protected] October 2005 Abstract. Surge current testing is considered one of the most important techniques to evaluate reliability and/or screen out potentially defective tantalum capacitors for low- impedance applications. Analysis of this test, as it is described in the MIL-PRF-55365 document, shows that it does not address several issues that are important to assure adequate and reproducible testing. This work investigates the effect of inductance of the test circuit on voltage and current transients and analyzes requirements for the elements of the circuit, in particular, resistance of the circuit, inductance of wires and resistors, type of switching devices, and characteristics of energy storage bank capacitors. Simple equations to estimate maximum inductance of the circuit to prevent voltage overshooting and minimum duration of charging/discharging cycles to avoid decreasing of the effective voltage and overheating of the parts during surge current testing are suggested. I. Introduction. High current spikes caused by power supply transients might result in short-circuit failures of tantalum capacitors and cause catastrophic consequences for electronic systems, including igniting the system. The probability of this type of failure is especially high for low-impedance circuits when inrush currents are limited mostly by the impedance of the capacitor itself [1]. Recently, these problems have gained yet more importance due to proliferation of distributed- power architecture systems and low-voltage DC-DC converters.

  • Failure Mechanisms in Wet Tantalum Capacitors
    Electrocomponent Science and Technology (C) Gordon and Breach Science Publishers Ltd. 1976, Vol. 2, pp. 249--257 Printed in Great Britain FAILURE MECHANISMS IN WET TANTALUM CAPACITORS The Plessey Company Limited, Northants, U.K. (R eceived May 13, 19 75, in final form June 1 7, 19 75) The wet tantalum capacitor is well established in both power supply smoothing and timing applications and has a well proven high reliability. This paper reviews the mechanisms of the possible failures arising from mis-application or over-stressing. The effect of over voltage on the anodic oxide is considered and the influence of cathode structure on reverse voltage and ripple current capability is discussed. The silver cathode allows migration of silver ions through the electrolyte under appropriate conditions and hence produces a failure mechanism not present in the tantalum cathode device. The life of a wet tantalum unit is eventually limited by loss of water vapour leading to open-circuit. Results are presented for button style capacitors which suggest that this is in fact not a practical limitation. 1 INTRODUCTION whole is assembled in a suitable case.

Power Engineering 7HFKQLFNi6W Prague - 6, 166 27, Czech Republic Abstract Tantalum Hybrid electrolytic/electrochemical capacitors are very versatile compo- nents, used in a wide variety of applications. This paper deals with pulse discharge characte- ristics measurement and specific power determination of these capacitors. Capacitors ZLWK 100 V rated voltage were chosen for the measurement. The capacitors were repetitively dis- charged into a low resistance load. More than 140 surge discharges were made with each component. The results were statistically processed and are presented. Equivalent series resis- tance of Hybrid capacitors is calculated from these measurements and based on its magnitude the specific power of the components is determined. Simultaneously with tantalum Hybrid capacitors some aluminum electrolytic capacitors were measured and the results are presented as well. Based on these results the capacitors are then compared. Tantalum Hybrid capacitors have the highest volumetric specific power (related to its dimensions) in medium voltage range. Introduction Tantalum Hybrid capacitors take advantage of the best features of electrolytic and electrochemical capacitors. They combine an anode from an electrolytic capacitor, a cathode from an electrochemical capacitor and compatible electrolyte. The tantalum Hybrid capacitor is a series combination of an anodic dielectric oxide film capacitance, Ta2O5, and a high elec- trochemical capacitance, a film of the conductive metal oxide, RuO2.

  • Capacitors Capacitors
    Capacitors There seems to be a lot of hype and mystery concerning the sound of capacitors, the quality of capacitors and what capacitors actually do in a circuit. There are many types of capacitors including ceramic, polyester, polypropylene, polycarbonate silver mica, tantalum and electrolytic. Each has its own area of “expertise”. One type of capacitor will perform well in a particular application and perform poorly in another. A capacitor is simply two metal plates separated by a dielectric. An electrical charge is stored between these two plates. The plates and dielectric can be made form several different types of material. The closer the plates are, the higher the capacitance and the larger the area of the plates, the larger the capacitance. The dielectric material affects the capacitance as well. Here is some brief information about the particular types. Note: The unit of capacitance is the Farad. It is a very large unit and so we use the following to express capacitance Microfarad is one millionth of a farad. Picofarad is one millionth of a microfarad So 0.001mfd is equal to 1000 picofarad (pF) The above diagram shows a simple representation of a capacitor. The capacitor is shown in RED . In parallel with the plates of the capacitor is a resistance, InsInsIns-Ins ---ResRes of the insulation. Teflon has the highest resistance with polystyrene, polypropylene and polycarbonate coming in second. Third is polyester and then the ceramics COG, Z5U and XR7 with tantalum and aluminium last. Dap is the Dielectric Absorption. All capacitors when charged to a particular voltage and then the leads are shorted, will recover some of their charge after the short is removed.

  • MT-101: Decoupling Techniques
    MT-101 TUTORIAL Decoupling Techniques WHAT IS PROPER DECOUPLING AND WHY IS IT NECESSARY? Most ICs suffer performance degradation of some type if there is ripple and/or noise on the power supply pins. A digital IC will incur a reduction in its noise margin and a possible increase in clock jitter. For high performance digital ICs, such as microprocessors and FPGAs, the specified tolerance on the supply (±5%, for example) includes the sum of the dc error, ripple, and noise. The digital device will meet specifications if this voltage remains within the tolerance. The traditional way to specify the sensitivity of an analog IC to power supply variations is the power supply rejection ratio (PSRR). For an amplifier, PSRR is the ratio of the change in output voltage to the change in power supply voltage, expressed as a ratio (PSRR) or in dB (PSR). PSRR can be referred to the output (RTO) or referred to the input (RTI). The RTI value is equal to the RTO value divided by the gain of the amplifier. Figure 1 shows how the PSR of a typical high performance amplifier (AD8099) degrades with frequency at approximately 6 dB/octave (20 dB/decade). Curves are shown for both the positive and negative supply. Although 90 dB at dc, the PSR drops rapidly at higher frequencies where more and more unwanted energy on the power line will couple to the output directly. Therefore, it is necessary to keep this high frequency energy from entering the chip in the first place. This is generally done with a combination of electrolytic capacitors (for low frequency decoupling), ceramic capacitors (for high frequency decoupling), and possibly ferrite beads.
