DME4P1K-F is a metallized polyester film capacitor designed for DC applications in a miniature radial-leaded, mini-dipped package. It features a capacitance of 0.1 µF with a rated voltage of 400 Vdc and operates over a temperature range of -55°C to +125°C with 50% voltage derating above 85°C. The capacitor offers self-healing capability for shorts caused by overvoltage transients, with a dissipation factor of 1% maximum at 25°C and 1 kHz. With dimensions of 0.256 inches (6.5 mm) thickness, 0.472 inches (12.0 mm) height, and 0.492 inches (12.5 mm) length, this compact capacitor is ideal for space-constrained applications requiring reliable DC filtering and coupling.
