Product Overview
The MMKP82 is a double-sided metallized polypropylene film capacitor (box-type) designed for high voltage, high frequency pulse circuits. It features low loss, small internal temperature rise, a negative temperature coefficient of capacitance, and excellent flame resistance. This capacitor is widely used in electronic ballasts, energy-saving lamps, and SNUBBER and SCR commutating circuits. It utilizes a polypropylene film dielectric with a double-sided metallized polyester film as electrodes, forming a non-inductive configuration with tin-plated copper wire leads and flame-retardant epoxy resin potting.
