TDK Corporation presents a new series of EPCOS MKP Y2 capacitors for EMI suppression. In contrast to conventional types that are designed for rated voltages of 300 V AC, these new capacitors offer a permissible rated voltage of 350 V AC. The capacitances of the B3203* series range from 4.7 nF to 1.2 µF. Even under harsh environmental conditions, the capacitors offer a stable capacitance value. They are certified according to IEC 60384-14:2013/AMD1:2016 and classified in accordance with "Grade III high robustness under high humidity Test B". This is verified by a temperature, humidity, bias (THB) test at 85 °C, 85 % relative humidity and 350 V AC operating voltage, at which a capacitance drop of no more than 10 percent may occur. The maximum operating temperature is 110 °C.

The capacitors are approved in accordance with UL and EN and qualified to AEC-Q200. Depending on their capacitance, they are available with a lead spacing of 15 mm (B32032*), 22.5 mm (B32033*), 27.5 mm (B32034*), or 37.5 mm (B32036*). The case and the epoxy resin sealing comply with UL94 V-0.

The possible applications of the new Y2 capacitors include EMI suppression in filters that are subjected to harsh environment conditions and demand higher rated voltages, such as those in photovoltaic inverters or automotive applications.
