Applications

For forced commutation of SCRs such as in inverters and choppers these capacitors are ruggedly designed to carry heavy currents. They employ a non-inductively wound oil impregnated paper polypropylene mixed dielectric coil with aluminium foil as electrode. Encased in aluminium can and offered in axial threaded screw terminals these are generally popular in values from 0.1 υF to 2 µF and in voltage rating of 1200 VAC. A special construction feature provides for an explosion proof performance through the means of an open circuiting of the element when excessive current flows through the capacitor under fault conditions.
