Capacitors protect against mains overvoltages

30 June 2004 Circuit & System Protection

Wima now offers RFI capacitors with polypropylene dielectric in addition to the metallised paper series. The Wima MKP-X2 and Wima MKP-Y2 series are available with capacitance values from 1000 pF through 2,2 µF and rated voltages of 275 V a.c. and 300 V a.c. respectively in the classes X2 and Y2. They have the ENEC/VDE approval according to DIN EN 132 400/IEC 60384-14/2 as well as UL 1414/CSA C 22.2 No. 1 (cULus).

The new ranges feature high capacitance values and small box sizes. With these series the company offers a wide range of safety-relevant Wima RFI capacitors. Besides the leaded versions with paper or Polypropylene dielectric it also includes SMD capacitors with metallised paper dielectric.
