Product Overview
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 utilized in absorption and resonance circuits, offering features such as a non-inductive winding structure, flame-retardant plastic casing, and epoxy resin encapsulation. Typical applications include switching power supplies, electronic ballasts, motor control, and TV vertical deflection circuits. They are characterized by low loss and minimal internal temperature rise.
