Multilayer Ceramic Chip Capacitors Our compact SMD type capacitors with laminated dielectric possess (MLCC) outstanding high- characteristics and heat resistance. They can be broadly divided into 2 types depending on their : Type 1 products SMD Type (temperature compensating) feature extremely small changes in capacitance due to temperature, while Type 2 products (high dielectric constants) are able to support relatively large capacitance values, but have larger rates of change due to temperature than Type 1.

MLCC with Dipped Radial Lead These are laminated ceramic chip capacitors bonded to lead and coated with resin. They combine the characteristics of laminated ceramic chip Ceramic Capacitors capacitors with benefits such as reduced mechanical and thermal stress due to their lead wires, and insulation and temperature shielding effects due to their resin coating. They are also effective in measures against capacitor "singing".

Lead Type Disc Type Capacitors with Lead These are disc-shaped ceramic capacitors with lead wires, able to support (High Voltage Ceramic Capacitors) medium to high voltages up to 6 kV. Their outer resin coating is compliant with halogen-free specifications, and their lineup includes a safety standardized product series which has obtained safety standard certifications from various countries, as well as a series compliant with the AEC-Q200 standard required for passive components in automotive applications.

These capacitors use an aluminum film and solution, featuring large capacitance but also having properties of polarity. TDK offers a varied Aluminum Electrolytic Capacitors lineup of aluminum electrolytic capacitors which includes radial lead, axial lead, screw terminal, and snap-in terminal types.

These capacitors use plastic film as dielectric with ultra-thin evaporated metallization layer. The self-healing capability is one of the main features. The Film Capacitors capability to withstand a wide range of AC and DC voltages, together with high current and temperature, makes them suitable for many applications in the range from a few hundreds watts up to several megawatts.

These are ceramic capacitors which can support ultra-high voltages up to 50 kV. Their use of paraelectric ceramics makes them highly stable and reliable with Ultra High Voltage Ceramic Capacitors regard to voltage. They also have excellent mechanical strength due to their simple structure.

Developed to stabilize the voltage of DC link circuits, our CeraLink™ capacitors are remarkably compact with PLZT (lead lanthanum zirconium titanate) CeraLink™ Capacitors ceramics as their base materials. They show exceptionally low ESL (Equivalent Series ) values and also have superb heat resistance.

EDLCs are special capacitors with characteristics between those of a capacitor and a battery (secondary battery). By causing to adhere to the surface of Electric Double-Layer Capacitors activated which have been soaked in electrolyte solution, (EDLC / Supercapacitors) an Electric Double Layer is formed to accumulate , giving these power storage devices extraordinarily large capacitance and .
