TDK has a series of EPCOS MKP AC capacitors suitable for filter applications. The B33331V * series of components are suitable for a rated voltage of 460VRMS, corresponding to a peak voltage of 650V, and have a capacitance range of 2µF to 50µF. Both cans and cans are made of aluminum, so the overall design is robust. Depending on the type, sizes range from 30mm x 55mm to 50mm x 100mm (D x H).
Even under severe conditions, the reliability of the new capacitors has been proven in 85 ° C, 85% relative humidity, and temperature, humidity, and bias (THB) tests for 1,000 hours of rated voltage. The life expectancy according to IEC 61071 is at least 100,000 hours. If the capacitor box is subjected to extreme pressure due to an overload, an integrated overvoltage disconnect safety device isolates the two terminals from the windings.
This device can be used as an output filter for photovoltaic inverters, frequency converters and UPS.
