Product Overview
The MMKP82 is a box-type, double-sided metallized polypropylene film capacitor designed for high-frequency DC and pulse applications in electronic equipment. It features a non-inductive winding structure with a metallized polyester film and metallized polypropylene film composite. The capacitor is encapsulated in a flame-retardant plastic case and epoxy resin, offering good dimensional consistency and low loss with minimal internal temperature rise. Typical applications include switching power supplies, electronic ballasts, motor control, and TV vertical deflection circuits.
