Capacitors Demystified: Practical Information on Capacitor Usage in EE133
EE133–Winter 2004 Capacitors Demystified Capacitors Demystified: Practical information on capacitor usage in EE133 Why do I need to read this? Despite all we know about capacitors from previous exposure (including everyone’s favorite capacitor fact – ‘Well, I know the voltage across a capacitor cannot change instantaneously!’), there is a quite a bit about the (good) properties and (bad) non- idealities of these devices that effects the way they are actually used in RF circuits. So, with the practical predisposition of EE133, let’s take another look at our old friend… The Starting Line-up Like fine cheeses or candy bars, capacitors come in wide variety of sizes, shapes, and prices- and they can be made from a host of different materials (except for nougat). However, all of these characteristics are interrelated because, in classic Murphy fashion, a capacitor that ranks well in one or two of these properties is usually terrible in the other categories. The physical size and shape are only of marginal importance to us since the former is pretty much irrelevant at the size of our solder board and the latter is only for aesthetics (which is a foreign term to EE’s anyway). But, the composite material is an important factor in determining the behavior of the capacitor, so for the purpose of this class we will identify four major types (Refer to page 21 of “The Art of Electronics” by Horowitz & Hill for a more complete listing of capacitor families): Material/Comments Picture Ceramics (10 pF – 22µF): Inexpensive, but not good at high frequencies Tantalum (0.1µF – 500µF): Polarized, low inductance Electrolytic (0.1µF – 75µF): Polarized, not good at high frequencies (NOTE: longer lead is usually the positive terminal) Silver Mica (1 pF – 4.7 nF): Expensive with only small capacitive values, but great for RF 1 EE133–Winter 2004 Capacitors Demystified Some Commonly Asked Questions about Capacitors Resistors are color-coded. -
Distribution Transformers
Shoemaker_CH15.qxd 13/07/06 11:43AM Page 15.1 CHAPTER 15 DISTRIBUTION TRANSFORMERS The purpose of a distribution transformer is to reduce the primary voltage of the electric distribution system to the utilization voltage serving the customer. A distribution trans- former is a static device constructed with two or more windings used to transfer alternating- current electric power by electromagnetic induction from one circuit to another at the same frequency but with different values of voltage and current. Figure 15.1 shows distribution transformers in stock at an electric utility company ser- vice building. The distribution transformers available for use for various applications, as shown, include pole-type (Figs. 15.2 and 15.3), pad-mounted (Fig. 15.4), vault or network type (Fig. 15.5), and submersible (Fig. 15.6). The distribution transformer in Fig. 15.2 is self-protected. It is equipped with a lightning arrester, a weak-link or protective-link expulsion-type fuse (installed under oil in the trans- former tank), a secondary circuit breaker, and a warning light. The transformer primary bushing conductor is connected to one phase of the three-phase primary circuit through a partial-range current-limiting fuse. The transformer tank is grounded and connected to the FIGURE 15.1 Electric utility distribution storage yard. Forklift trucks are used to load transformers on line trucks.

Beam, Coupling Impedance
Beam Impedance, Coupling Impedance, and Measurements using the Wire Technique John Staples, LBNL Beam, Coupling Impedance When a particle beam of current I travels through a structure, it may give up some of its energy to that structure, reducing its energy. The energy loss may be expressed as a voltage V, and the beam impedance Zb of the structure itself may be expressed as V loss Z b = I beam The structure may be a monitor device, where a signal V is generated by the beam and detected. In this case, we can define a coupling impedance Zp for the structure V monitor Z p = I beam In general, these are not the same, and each depends on the details of the structure itself. Stripline Monitor A beam bunch, as it travels down a pipe, induces images charges on the interior surface of the pipe. If the pipe is smooth and lossless, these charges do not affect the beam. An irregular beam pipe, however, will interact with the beam, as fields are induced in the beam pipe by the beam. The fields of a relativistic beam are concentrated along the direction of motion. One very useful type of monitor is the stripline monitor, which responds to the image charges. An electrode or electrodes are mounted in the beam pipe. Each end of the electrode is brought out and connected to a load. The electrode subtends and angle q. The geometry of the stripline resembles that of a microstrip, which has a characteristic surge impedance. The propagation velocity of an impulse along the stripline is assumed to be the speed of light c. -

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.
