944U161K801ABI Cornell Dubilier

Type 944U Polypropylene, DC Link Capacitors High Current, Low Profile for Inverter Applications Type 944U is specifically designed for use in high power DC filtering applications. The low inductance internal construction utilizes low loss metallized polypropylene for high ripple current capability. Male or female terminal options offer design flexibility in a rugged UL 94VO rated flame retardant plastic case and resin fill. High current ratings and robust mounting flanges make the 944U suited for inverter applications in electric vehicle power inverters, wind power inverters and motor drives. Highlights - Low Inductance - Low Profile - Low ESR - High Ripple Current - High Voltage Ratings Specifications Capacitance Range 33 to 220 F Capacitance Tolerance 10% standard Rated Voltage 800 to 1400 Vdc Operating Temperature Range -40 C to 85 C Maximum rms Current 74A 55 C Maximum rms Voltage 230 Vac Test Voltage between Terminal 25C 150% rated DC voltage for 10 s Test Voltage between Terminals & Case 25C 4 kVac 50/60 Hz for 60 s Life Test 5000 h 85 C, rated voltage RoHS Compliant Dimensions Construction Details 20 0.5 mm Case Material Plastic UL94V-0 M8 x 20mm H 0.5 mm Max Torque 8.5Nm Resin Material Dry Resin UL94V-0 Terminal Material Tin Plated Brass 5 mm M8 Stud 84.5 0.5 mm 45 1 mm Terminal UL Recognized E128034 construction only - unprotected 101 mm 6 0.5 mm 6 0.5 mm 15 mm 5.5 Max Torque 3Nm 5 mm 45 1 mm M5 Insert 84.5 0.5 mm 71.4 mm Terminal 90 H 0.5 mm M5 x 7.5mm Max Torque 2.5Nm Part Numbering System 944U 101 K 801 A A M Type Capacitance Tolerance Voltage Diameter D (mm) Height H (mm) Terminal 944U 101 = 100 F K = 10% 801 = 800 Vdc A = 84.5 A = 40 M = M8 Thd Stud 700 = 70 F 102 = 1000 Vdc B = 51 I = M5 Thd Insert 470 = 47 F 122 = 1200 Vdc C = 64 142 = 1400 Vdc CDE Cornell Dubilier 1605 E.
