Product Overview
The MMKP82 Double sided metallized polypropylene film capacitor (Box-type) is designed for high voltage, high frequency, and pulse circuits. It features a double-sided metallized polypropylene structure with low loss, small internal temperature rise, and a negative temperature coefficient of capacitance. Its excellent flame-resistant properties make it suitable for electronic ballasts, compact lamps, and SNUBBER and SCR commutating circuits. The capacitor utilizes a polypropylene film dielectric and double-sided metallized polyester film electrodes, with a non-inductive configuration and tin-plated copper leads, sealed with flame-retardant epoxy resin.
