The 947D311K122DCRSN is a polypropylene DC link capacitor designed for high current and high capacitance in inverter applications such as wind, solar, and UPS systems. It has a capacitance of 310 µF, a rated DC voltage of 1200 V, and operates within an ambient temperature range of -45 °C to 85 °C. The capacitor is housed in an aluminum can with a diameter of 116 mm and a height of 75 mm, featuring a 50 mm terminal spacing and an M6 insert terminal. Its maximum rms current is 90 A, with a typical ESR of 1.1 mΩ and ESL of 35 nH. The case has a thermal resistance of 0.9 °C/W from case to ambient and weighs 0.9 kg. The unit meets IEC 61071 standards and uses a UL94V-0 dry resin. The terminal mounting system supports a max torque of 10 Nm for the M6 insert.
