Cornell Dubilier Electronics Q Series film capacitors for medical defibrillator applications are in stock at New Yorker Electronics.

Designed specifically for today’s quick response and professional use defibrillators, the Q Series meets the reliability demands of Class III medical devices.

Used extensively in automated external defibrillators (AEDs), the series offers designers the highest in-class energy density and broadest range of packaging options. 

The Q Series capacitors are designed for use in monophasic and bi-phasic defibrillators with energy densities as high as 2 J/cc.

Some designs can deliver in excess of 500 joules when fully charged.

Voltage ratings range from 800Vdc to 6,000Vdc with capacitance values covering the range from 32 to 500μF. 

Standard packages include oil-filled metal cases or epoxy-filled plastic cases, both available in either round or oval configurations.

A multitude of terminations are available ranging from quick-connect blades to insulated wire leads. The company also has the capability of integrating capacitor windings into a custom moulded package to achieve the smallest possible profile and highest energy density for the end-device.
