Defibrillator Capacitors

Cornell Dubilier Electronics, Liberty, SC, has launched a series of film capacitors for medical defibrillator applications. The Q Series meets the reliability demands of Class III medical devices. Used extensively in automated external defibrillators (AEDs), the capacitors are designed for use in monophasic and biphasic defibrillators with energy densities as high as 2 J/cc. Some designs can deliver in excess of 500 J when fully charged. Voltage ratings range from 800 to 6,000 Vdc with capacitance values covering the range from 32 to 500 µF.
