Cornell Dubilier Film Paper Film Capacitors 105RSB122K4J

The part is a 1µF, 1200VDC radial lead film capacitor for high pulse and rms current applications, with a maximum operating temperature of 85°C and a minimum of -40°C. It has a dv/dt rating of 870 V/µs, a typical ESR of 4.1 mΩ at 100 kHz and 25°C, and a maximum RMS ripple current of 17.5 A at 70°C. The physical dimensions are 41.5 mm × 40 mm × 20 mm with lead spacing of 10.2 mm and terminal diameter of 1.2 mm. The capacitor uses a double metallized polypropylene film construction with flame-retardant epoxy resin coating (UL94V-0) and lead-free tinned copper leads. Its capacitance tolerance is ±10% at 1 kHz, and it has a dielectric strength of 160% of rated DC voltage or 150% of rated AC voltage applied for 2 seconds at 25°C.
