The MMKP82 series is a box-type, double-sided metallized polypropylene film capacitor designed for high-frequency DC and pulse applications in electronic equipment. These capacitors are suitable for absorption and resonant circuits, offering features such as a non-inductive winding structure, flame-retardant plastic casing, and epoxy resin encapsulation. Key applications include switching power supplies, electronic ballasts, motor control, and TV vertical deflection circuits.
