Supercapacitors

Cornell Dubilier (CDE) Supercapacitors are also known as ultracapacitors, double-layer capacitors, or electro-chemical double layer capacitors (EDLC). These supercapacitors offer a comprehensive range of capacitance values and voltages. The utilized CDE technology is used in various applications, from battery backup in smart meters to regenerative braking. Ranging from board-mountable coin types to radial form factors, these supercapacitors provide high-voltage modules with active or passive balancing. CDE Supercapacitors are ideal for wind turbines, mass transit, hybrid cars, consumer electronics, and industrial equipment applications.
