475MPW160K

The 475MPW160K is a metallized polypropylene film capacitor from Cornell Dubilier Electronics (CDE), part of the MPW series. It has a capacitance of 4.7 µF with ±10% tolerance and a rated voltage of 160 VDC (90 VAC). The capacitor is designed for DC link and DC filtering applications, as well as general-purpose AC applications (not across the line).

Key electrical characteristics include a low dissipation factor of 0.001 maximum at 1 kHz, insulation resistance of 10000 MΩ·µF at 100 VDC, and a dv/dt rating of 8 V/µs. Self inductance is less than 1 nH per mm of body plus lead length. The capacitance temperature coefficient is -200 ppm/°C to +100 ppm/°C. The load life is 2000 hours at 85°C with 125% rated voltage, and capacitance drift is less than 0.5% after 2 years at 40°C.

The capacitor is housed in an axial through-hole package with dimensions of 18.00 mm diameter by 34.00 mm length. It has lead-free tinned leads of 0.8 mm diameter and PC pin terminations. The operating temperature range is -55°C to 105°C, with voltage derating of 1.5% per °C above 85°C. The coating is flame retardant polyester tape wrap with epoxy resin end fills, meeting UL 94V-0.
