EMI suppression capacitors with high rated voltage

TDK Corporation has a series of robust EPCOS MKP X2 capacitors for EMI suppression. They are available now from Digi-Key. Compared with conventional X2 capacitors designed for rated voltages of 305VAC, these components offer a higher rated voltage of 350VAC. This makes them suitable for EMI suppression in input filters and output filters of photovoltaic inverters, for example. The capacitance range extends from 0.47µF to 10µF in accordance with the E12 series. Even under severe ambient conditions the capacitors are characterized by a stable capacitance, as verified in damp heat tests, in which the change in capacitance does not exceed 7.5% (test conditions: 1000 hours at 85C with a relative humidity of 85% and a voltage of 330VAC). The maximum operating temperature of the components is 110C.
