UFcapacitors MMKP82 is a double-sided metallized polypropylene film capacitor , designed as an advanced successor to traditional CBB81 capacitors. It combines ultra-compact dimensions with superior electrical performance, making it ideal for high-voltage, high-frequency, and pulse applications in modern power electronics.
Constructed with dual-sided metallized polypropylene film + dielectric polypropylene (PP) film, enabling higher current density and reduced volume compared to single-sided CBB81 capacitors.
Self-healing properties ensure long-term reliability by automatically isolating defects, minimizing failure risks.
Enhanced Electrical Performance
Ratedvoltage: 250VDC, 400VDC, 630VDC, 1000V DC, 1600V, 2000V DC DCsuitable for demanding circuits.
Capacitance Range: 220pF~3.9uF
High pulse handling: Superior dv/dt and di/dt tolerance, ideal for snubber, resonant, and energy absorption circuits.
