The MP9-21021K is a high-reliability, three-phase AC filter capacitor module specifically engineered for use in ABB variable frequency drives (VFDs). It features three independent 64 μF metallized polypropylene (MKP) capacitor elements housed in a compact, robust epoxy-impregnated rectangular housing (3×64 μF total per phase configuration). Rated for continuous operation at 690 VAC (50/60 Hz) and with a DC withstand voltage of 1100 VDC, it meets stringent industrial requirements for harmonic filtering, DC-link stabilization, and EMI suppression in demanding motor drive applications. Key attributes include self-healing capability, low ESR/ESL, flame-retardant UL94-V0 housing, and RoHS compliance. Compatible with ABB ACS800, ACS880, and similar high-power drive platforms where space, thermal stability, and long service life (>100,000 hrs @ 70°C) are critical.
