Type 935C, Polypropylene Capacitors for High Frequency Filtering High Current Capacitors for Switching Power Supplies Type 935 metallized polypropylene capacitors are designed for filtering applications in switching power supplies that operate in the 20-100 kHz range. Their low ESR, high current and high capacitance gives them an advantage over general purpose types. This series is UL recognized for construction only under UL File Number E128034(N). Highlights - Low ESR - High current - High capacitance - Self healing - UL recognized - Available with lugs Specifications Capacitance Range 1.0 to 30.0 µF Capacitance Tolerance ±10 % (K) Standard; ±5% (J) Optional Rated Voltage 100 to 400 Vdc (70 to 250 Vac, 60 Hz) Operating Temperature Range –55 ºC to 105 ºC* *Full rated voltage at 85 ºC - derated linearly to 50% rated at 105 ºC Maximum rms Current Check tables for values Insulation Resistance 200,000 MΩ x µF Test Voltage between Terminals @ 25 ºC 200% rated DC voltage for 60 s Test Voltage between Terminals & Case @ 25 ºC 3 kVac @ 50/60 Hz for 60 s Life Test 1,000 h @ 85 ºC, 150% rated DC voltage Life Expectancy 60,000 h @ rated Vdc, 70 ºC 30,000 h @ rated Vac, 70 ºC RoHS Compliant Dimensions Construction Diagram Construction Details Case Material UL510 Polyester Tape Wrap Resin Material UL94V-0 Epoxy Fill Terminal Material Tin Plated Copper d 41 mm Min L 1.5 mm L1 1.57 mm 3.96 1.3 mm L 1.98 mm 41 mm Min D Max 9.144 1.3 mm 7.93 mm Min 0.8 0.05 mm D Max CDE Cornell Dubilier • 1605 E.
