Polypropylene Film Capacitors (KNB2530 RFI Class Y1)

Class Y capacitors are suitable for applications where the breakdown of the capacitor can lead to a dangerous electric shock. Metallized polypropylene film capacitors KNB2530 RFI Class Y1 have long life expectancy and they can withstand pulse peak voltage in service up to 8.0 kV. Rated voltage range 440 AV C. Permissible continuous (DC) voltage: 3.0 kV.

 

Y1 capacitors are used in special applications with higher peak voltage requirements and:

  • power supplies / SMPS,
  • industrial applications,
  • household equipment with a fixed mains connection (EN 60065-1).

The main area of application for the newly defined Y1 class is as a ratio interference suppression capacitor between the primary and secondary ground of SMPS.
