WMF05W1K Description

Short technical summary and product information.

The Cornell Dubilier WMF05W1K is a 1 µF polyester film/foil capacitor rated for 50 VDC. It features a ±10% tolerance and is housed in an axial leaded package measuring 14.30 mm diameter by 34.90 mm length. The capacitor uses a UL510 polyester tape wrap case with UL94V-0 epoxy fill and tin plated copper-clad steel leads.

 

This component is designed for general purpose applications and offers a dissipation factor of 0.75% maximum at 25°C and 1 kHz. It provides a minimum insulation resistance of 100,000 MΩ (or 30,000 MΩ·µF) at 25°C. The dV/dt rating is 660 V/µs, indicating suitability for circuits with moderate voltage transients.

 

The operating temperature range spans -55°C to 125°C, with full rated voltage at 85°C and linear derating to 50% rated voltage at 125°C. The through-hole mounting with axial leads makes it compatible with traditional PCB layouts.
