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

Usage Rules
- Operating Range: Do not exceed upper category temperature. Avoid overload and maximum pulse current.
- Handling: Avoid repeated squeezing at the lead root. Be cautious of lead tips.
- Soldering: Solder iron tip temperature should not exceed 350C for no more than 3 seconds. For wave soldering, refer to specific temperature and time limits (TP 110C/120s, Ts 120C/45s; for P7.5mm, T4mm, time < 4s). Not suitable for reflow soldering.
