The 930C4S56K-F is a Type 930 metallized polypropylene capacitor designed for DC filtering in high-voltage switching power supplies. This 56 µF capacitor is rated for 400 Vdc (250 Vac) operation with a ±10% capacitance tolerance and features low dissipation factor and self-healing properties. The device has a physical dimension of 8.0 mm diameter and 19.0 mm length, with a dV/dt rating of 49 V/µs at 25°C. Operating across a temperature range of -55°C to 105°C with full rated voltage at 85°C and linear derating to 50% at 105°C, this capacitor is ideal for blocking, filtering, bypassing, coupling, and decoupling applications in power conversion and high-frequency switching circuits. The UL-recognized construction with polyester tape wrap and epoxy fill ensures reliable performance in demanding industrial and commercial applications.
