Film capacitors: Robust industrial grade X2 capacitors with a rated voltage of 350 V AC
TDK Corporation presents a new series of robust EPCOS MKP X2 capacitors for EMI suppression. Compared with conventional X2 capacitors designed for rated voltages of 305 V AC, these new components offer a higher rated voltage of 350 V AC. This makes them suitable for EMI suppression in input filters – specifically for applications on the North American market – and output filters of photovoltaic inverters, for example.
The capacitance range extends from 0.47 µF to 10 µF in accordance with the E12 series. Even under severe ambient conditions the new capacitors are characterized by a stable capacitance, as verified in damp heat tests, in which the change in capacitance does not exceed 7.5 percent (test conditions: 1000-hours at 85°C with a relative humidity of 85 percent and a voltage of 330 V AC). The maximum operating temperature of the components is 110 °C.
The X2 capacitors are approved in accordance with UL and EN and, depending on the capacitance, are available with a lead spacing of 27.5 mm (B32924*4*) or 37.5 mm (B32926*4*). Both the casing and the epoxy resin sealing material comply with the UL 94 V-0 standard.
The capacitors are especially suitable for applications with higher demands in terms of current capability, as well as capacitive power supplies.
