Product Overview
The MMKP82 series are box-type, double-sided metallized polypropylene film capacitors designed for high-frequency DC and pulse applications in electronic equipment. These capacitors feature a non-inductive winding structure with a metallized polyester film and metallized polypropylene film composite. They are encapsulated in flame-retardant plastic cases and epoxy resin, ensuring good dimensional consistency and low loss with minimal internal temperature rise. Typical applications include switching power supplies, electronic ballasts, motor control, and TV correction circuits.
