Robust 3-phase filter capacitors
10 October 2018, Passive Components
TDK introduced the new, extensive B3237* series of EPCOS MKD 3-phase capacitors for filter applications. The capacitors cover a voltage range from 250 VRMS to 850 VRMS in 10 stages, and are available with capacitances of between 3 x 10 μF and 3 x 400 μF.
Depending on the type, the capacitors are designed for currents of up to 60 A. Internally, the capacitances are connected in three phases. In accordance with IEC 61071, the life expectancy is about 100 000 hours at the rated voltage, the maximum drop in capacitance being 3% from the initial value.
The capacitors are accommodated in robust aluminium cans with M12 bolts on the bottom. Depending on the capacitance, they have a diameter of between 75 mm and 136 mm, and a height of between 163 mm and 350 mm. The capacitors are designed for an operating temperature of between -40°C and +70°C.
They are UL-listed and have an internal overpressure disconnector that isolates all three internal capacitors from the feed lines. Typical applications are output filters in power electronic devices such as converters and inverters for industrial and energy applications.
