The MP9-21021K is a high-reliability, three-section metallized polypropylene (EC) film capacitor specifically engineered for AC harmonic filtering and DC-link stabilization in industrial variable frequency drives. It features three independent 64 μF sections (total 192 μF equivalent when paralleled per design), rated for continuous operation at 690 VAC (50/60 Hz) and peak DC voltage up to 1100 VDC. Housed in a compact, flame-retardant (UL94 V-0) epoxy-impregnated rectangular case with M5 screw terminals, it offers low ESR, high ripple current capability, self-healing properties, and extended service life (>100,000 hours at 70°C). Optimized for integration into ABB ACS880, ACS800, and similar high-performance drive systems, the MP9-21021K meets IEC/EN 61071, IEC/EN 61881, and RoHS requirements. Includes integrated discharge resistors (typ. 10 MΩ per section) for safe residual voltage dissipation.
