The TDK B32378A6706J000 is a three-phase AC filter capacitor from the FilterCap MKD AC series, designed for general-purpose power electronic applications such as harmonic filtering, power factor correction (PFC), and motor drive systems. It features a star connection with a neutral terminal, metallized polypropylene film dielectric, and a self-healing overpressure disconnector for safety. The capacitor is housed in a robust aluminum case with an M12 mounting stud and is UL/CSA certified for operation up to 600 VRMS line-to-line.
Key Features
- Three-Phase Star Connection: Four-terminal design (L1, L2, L3, N) for wye configurations.
- Self-Healing Technology: Metallized polypropylene film ensures reliability and long life.
- Safety Device: Integrated overpressure disconnector for fault protection.
- High Current Capability: Designed for high RMS and peak currents in AC applications.
- Low Loss: Very low dissipation factor (tan δ ≤ 1.0 x 10-3).
- Long Service Life: 100,000 hours life expectancy at rated voltage and +85°C hot-spot.
- Safety Certified: UL 810, CSA C22.2 No. 190 certified (File E487229).
- RoHS Compliant: Non-PCB, soft polyurethane resin filling.
