Overview: The TDK B32373A3257J030 is a high-power film capacitor from the B32373 series, part of the FilterCap MKD-AC single-phase range for general-purpose applications. It features a 250µF rated capacitance and a 330VAC (460VDC) voltage rating, housed in a robust aluminum can with M10 screw terminals. Utilizing metallized polypropylene film and self-healing technology, this capacitor is designed for high reliability, low losses, and long service life in demanding power electronic environments such as motor drives and power supplies.
Key Features:
- Metallized polypropylene film dielectric with self-healing technology
- High-power M10 screw terminals for secure, high-current connections (100A max)
- Long life expectancy: 100,000 hours at rated voltage and +85°C hot-spot
- Low dissipation factor (tan δ ≤ 1.0 x 10⁻³ at 100Hz)
- Non-PCB, soft polyurethane resin filling
- Overpressure disconnector safety device; naturally air-cooled
- Safety approvals: UL 810, CSA C22.2 No. 190 (Protected, 10k AFC)
