Defibrillator capacitors provide high energy density

Cornell Dubilier Electronics now offers its Q Series film capacitors for medical defibrillator applications. Created particularly for today’s quick response and professional use defibrillators, the series satisfies the reliability demands of Class III medical devices. Employed extensively in AEDs, the series provides designers the highest in-class energy density and widest range of packaging options.

These capacitors are intended for employment in monophasic and bi-phasic defibrillators with energy densities as high as 2J/cc. Some designs can produce more than 500 joules when fully charged. Voltage ratings range from 800VDC to 6,000VDC with capacitance values, including the range from 32μF to 500μF.

Standard packages comprise oil-filled metal cases or epoxy-filled plastic cases, both offered in round or oval configurations. An abundance of terminations are offered, ranging from quick-connect blades to insulated wire leads. The company can also integrate capacitor windings into a custom-moulded package to deliver the smallest possible profile and highest energy density for the end-device.
