CDE expands capabilities in high-energy storage, pulse-discharge capacitors

Cornell Dubilier Electronics Inc. (CDE) has expanded its portfolio of standard and custom high energy storage, pulse-discharge capacitors. These specialized devices are designed for applications requiring repetitive high energy and high voltage charge/discharge cycles. The capacitor technology is based on film dielectric with self-healing metallized or high current discrete foil electrodes, depending upon application requirements. There are both dry and oil-impregnated types, offered with a broad range of plastic or metal packaging configurations and a variety of terminal options.

Designed to deliver large amounts of energy in short bursts, the devices target end-product applications in external defibrillators, industrial lasers, critical military applications, pulse forming networks and more. These specialized markets are growing more rapidly than many others in power electronics, and often require custom products. Reliability of these capacitors is paramount, and must therefore be designed, constructed and tested to deliver consistent performance over the life of the application.

Due to the critical nature of their applications, CDE stresses the need to gain a thorough understanding of the performance requirements and will work collaboratively with customers to develop an optimal solution. Designs are typically qualified after considerable testing by CDE and in the customers’ own testing programs.

The high energy storage, pulse-discharge capacitors are designed and built in the U.S. with voltage ratings up to 100 kV and peak discharge current ratings of up to 250 kA.
