Pulse Discharge Capacitors
For the most challenging medical, industrial and military pulsed power applications
Knowles' Cornell Dubilier brand announces a major product expansion of standard and custom high-energy storage, pulse-discharge capacitors. These are specialized devices, designed for applications requiring repetitive high energy and high voltage charge/discharge cycles. The capacitor technology is based on film dielectric with self-healing metalized 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, these devices are aimed at 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. The 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, we stress 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 Cornell Dubilier and in the customers’ testing programs.
Cornell Dubilier’s high energy storage, pulse-discharge capacitors are designed and built in the USA, with voltage ratings up to 100 kV and peak discharge current ratings of up to 250 kA.

Type QAS, Arc Suppressor/Snubber Network
Type QAS will extend the operating life of electronic and electro-mechanical devices by reducing and/or eliminating the electrical arcing, noise, and EMF. These electrical conditions often cause early failures in relays, switch contacts, and solid-state components such as SCRs and TRIACs.

3 CELL DSF & DGH
Three-cell devices offer greater energy potential and power output than single or dual-cell parts in standard PCB layouts
3-cell DSF & DGH capacitors provide very fast power discharge that cannot be matched by conventional capacitors or batteries. That large capacity makes it possible to support brief power interruptions, supplement batteries, or even be used in place of batteries in many applications.

TYPE MXT, X2, EMI/RFI Suppression Capacitors, Harsh Environment
Type MXT Series Metallized Polypropylene Film Capacitor, designed to suppress conducted electromagnetic/radio frequency interference (EMI/RFI) at a circuit’s power input. These capacitors are perfect for use in harsh environments having met the demanding 85/85 THB (Temperature, Humidity, Bias) test requirements. Class X2 capacitors, like the MXT, are typically connected across the AC input to prevent interference from spreading through power lines or other devices on the same circuit.
