CD42FD503JO3 Description

Short technical summary and product information.

The CD42FD503JO3 is a standard dipped silvered mica capacitor from Cornell Dubilier Electronics (CDE). It offers a nominal capacitance of 0.05 µF with a tolerance of ±5% and a rated voltage of 500 V. This capacitor is housed in a radial through-hole package with an epoxy case and copper clad steel terminals with a nickel undercoat and 100% tin finish.

 

It features a minimum dV/dt pulse capability of 100,000 V/µs and a dielectric strength test of 200% of rated voltage. The operating temperature range spans from -55 °C to +125 °C, making it suitable for a wide variety of environments. The body dimensions are 37.60 mm in length, 11.90 mm in width, and 23.40 mm in height, with a lead spacing of 27.00 mm.

 

This capacitor is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited). It is designed for general-purpose applications requiring stable capacitance over a broad temperature range, such as timing circuits and close-tolerance filtering.
