Cornell Dubilier Film Paper Film Capacitors 305PPS850KS

The 305PPS850KS is an axial lead, metallized polypropylene film capacitor designed for high dv/dt applications such as inverters, converters, and switching power supplies. It has a DC voltage rating of 850 V, with a surge voltage of 1300 V and an AC voltage rating of 500 V. Capacitance is 3 µF with a tolerance of ±10% at 1 kHz and 25°C. The component exhibits a dissipation factor of ≤0.0001 at 1 kHz and 25°C, insulation resistance of ≥30,000 MΩ·µF at 25°C, and self-inductance of less than 1 nH per mm of lead spacing. It operates from -40°C to +85°C and has a life expectancy of 100,000 hours at 70°C under DC voltage. The case size is 29 mm in diameter by 59 mm in length, with lead spacing of 1.2 mm and lead-free tinned copper terminals. The construction includes flame-retardant polyester tape wrap and epoxy resin end fill rated UL94V0.
