Featured Products

Aluminum Electrolytic Capacitors: These are used in power supplies, motor run applications, and audio equipment.

Ceramic Capacitors: A ceramic capacitor uses a ceramic material as the dielectric. Ceramic capacitors are the common types of capacitors used in most electrical instruments as they are more reliable and cheaper to manufacture.

Film Capacitors: Including polyester, polypropylene, and metalized film capacitors for various applications like filtering, coupling, and bypassing.

Mica Capacitors: Originally the company's specialty, mica capacitors are still manufactured for high-frequency and precision applications.

Polymer Capacitors: CDE Polymer Capacitors offer a broad range of technologies that can be used in the most demanding applications. Polymer capacitors are capacitors which use conductive polymers as the electrolyte. They use solid polymer electrolytes instead of liquid or gel electrolytes that are found in ordinary electrolytic capacitors.

Supercapacitors/Ultracapacitors: Used for energy storage and backup power in applications requiring rapid charge/discharge cycles.

Tantalum Capacitors: CDE offers tantalum electrolytic capacitors known for their high reliability and capacitance stability.
