CD19FD501FO3F is a standard dipped silvered mica capacitor from Cornell Dubilier's CD19 series, designed for timing and close tolerance applications requiring stable capacitance over a wide temperature range. This capacitor features a 500 pF capacitance value with ±1% tolerance (F) and a rated voltage of 500 Vdc. The CD19 series offers dimensions of approximately 0.64 in (16.3 mm) length, 0.51 in (13.0 mm) height, and 0.20 in (5.1 mm) thickness, with lead spacing of 0.334 in (8.7 mm) and lead diameter of 0.032 in (0.8 mm). Operating over a temperature range of -55°C to +125°C, these capacitors provide excellent stability and are suitable for applications requiring high dV/dt pulse capability of 100,000 V/µs minimum.
