B32377/B32378 Series of EPCOS MKD 3-Phase Capacitors

TDK Corporation's B32377 and B32378 series are EPCOS MKD 3-phase capacitors for filter applications. The capacitors have a voltage range from 250 V_RMS to 1000 V_RMS in ten stages and capacitance between 3x10 µF and 3x400 µF.

The B32377 and B32378 capacitors are designed for currents of up to 72 A, depending on the type. Internally, the capacitors are connected in three phases. The life expectancy is about 100,000 hours at the rated voltage, in accordance with IEC 61071, with a maximum drop in capacitance of 3 percent from the initial value.

The capacitors are enclosed in robust aluminum cans with M12 mounting bolts on the bottom. They have a diameter of between 75 mm and 136 mm, and a height of between 163 mm and 350 mm, depending on the capacitance. The operating temperature is -40°C and +70°C.

UL-listed with an internal overpressure disconnect that isolates all three internal capacitors from the feed lines makes these capacitors well-suited for output filters in power electronic devices such as converters and inverters for industrial and energy applications.
