Product Overview
The Dongguan Keya Electronic Technology Co., LTD MMKP82 is a double-sided metallized polypropylene film capacitor (box-type). It features low loss, small internal temperature rise, a negative temperature coefficient of capacitance, and excellent flame resistance. This capacitor is widely used in high-voltage, high-frequency pulse circuits, electronic ballasts, compact lamps, and SNUBBER and SCR commutating circuits. It utilizes a polypropylene film dielectric with a self-healing metallized polyester film electrode, a non-inductive configuration formed by dual-end metallization, and a tin-plated copper wire lead. The capacitor is encapsulated with flame-retardant epoxy resin.
