WMF6S22K-F is a Type WMF polyester film/foil capacitor with axial leads designed for commercial and industrial applications requiring high voltage and high peak current performance. This 0.022 µF capacitor is rated for 630 Vdc operation with a capacitance tolerance of ±10% at 1 kHz and 25°C, featuring a dV/dt rating of 5800 V/µs and very low inductance due to its non-inductive wound construction. The capacitor has a body diameter of 8.5 mm and length of 23.8 mm with 0.6 mm lead diameter, and is constructed with UL510 polyester tape wrap case material, UL94V-0 epoxy fill, and tin-plated copper-clad steel terminals. It operates reliably over the temperature range of -55°C to 125°C with full rated voltage at 85°C, derated linearly to 50% at 125°C, making it ideal for high-frequency switching circuits, power supplies, and applications with demanding peak current requirements.
