The 947D571K122DGRSN is a polypropylene DC link capacitor in an aluminum can case, designed for high current and high capacitance in inverter applications such as wind, solar, and UPS systems. It has a capacitance of 570 µF, a rated DC voltage of 1200 V, and a maximum ripple current of 85 A at 55 °C. The capacitor measures 116 mm in diameter and 126 mm in height, with a terminal spacing of 50 mm and a stud mount (M8 x 16mm, 10 Nm max torque). Thermal resistance is 0.9 °C/W for case-to-ambient and 1.8 °C/W for case-to-core. It is rated for an operating temperature range of -45 °C to 85 °C, has a mass of 1.5 kg, meets IEC 61071 standards, and uses UL94V-0 dry resin for insulation. The case is sealed with a plastic insulator cap and tin-plated brass terminals.
