CORNELL DUBILIER 945U321K751DMI

Type 945U Polypropylene, DC Link Capacitors High Capacitance, Screw Terminal Case for Inverter Applications Type 945U uses advanced metalized film technology to achieve long-life, high reliability in DC link applications. High voltage and high current ratings packaged in screw-terminal cases allow for replacement of series-parallel banks of aluminum electrolytic capacitors in high ripple current application. Suited for wind and solar power inverters. Highlights Advantages over Electrolytics - Exceptionally Low ESR - High Ripple Current - Non-Polar - High Voltage ratings - Dry Construction - no Electrolyte Specifications Capacitance Range 65 to 500 µF Capacitance Tolerance ±10% standard Rated Voltage 600 to 1000 Vdc Operating Temperature Range with Ripple -55 ºC to 85 ºC Maximum rms Current 47A @ 50 ºC Maximum rms Voltage 230 Vac Test Voltage between Terminal @ 25ºC 130% rated DC voltage for 60 s Test Voltage between Terminals & Case @ 25ºC 3 kVac @ 50/60 Hz for 60 s Life Test 2000 h @ 85 ºC, 125% rated voltage RoHS Compliant Dimensions Construction Details Case Material Aluminum with Black PVC Sleeve Resin Material Dry Resin UL94V-0 17.4 Terminal Material Tin Plated Brass 0.05 mm ¼-28 x 0.437" Deep Internal Thread 31.75 ±0.25 mm 3.18 0.25 mm 1/4 - 28 x 0.50” Round Head Screws provided H Shown with optional M12 Mounting Stud ±1.57 mm Lock Washer and Hex Nut provided 15.0 mm 76.8 mm Min Min ¼-28 x 0.50" Round Head Screws Provided CDE Cornell Dubilier • 1605 E.
