X2Y2 Capacitors
Y2 Capacitors, which are used to bridge operational insulation, are classified as Y1, Y2, Y3 or Y4 according to type of bridged insulation as well as AC and peak voltage ratings. Y1 class capacitors are rated up to 500 Vac, with a peak test voltage of 8 kV. Commonly used Y1 capacitors in DAIN are 222M 250Vac and more according to the requirement in application.
