The 947D421K122CGRSN is a polypropylene DC link capacitor designed for high-current inverter applications, with a capacitance of 420 µF, a rated voltage of 1200 Vdc, and a maximum rms current of 69 A. It uses an aluminum can case with a diameter of 100 mm and height of 126 mm, and features an M8 stud mounting with a 50 mm terminal spacing. The capacitor meets IEC 61071 standards, operates from -45 °C to 85 °C, and has a thermal resistance of 1.1 °C/W from case to ambient. The case is sealed with UL94V-0 rated dry resin, and terminals are tin-plated brass with a 10 Nm maximum torque rating for the M8 stud.
