Polypropylene Film Capacitors (KNB 1580 RFI Class X2)

Class X capacitors are suitable for applications where there is no danger of electrical shock in case of breakdown. Metallized polypropylene film capacitors type KNB1580 Class X2 with rated voltage 305 VAC or 310VAC have a very stable capacitance over long operational life. They can withstand peak pulse voltage in service up to 2.5 kV.

 

The capacitor type KNB1580 includes all advantages of a CD version. They can be used in parallel or serial connection with the supply mains.
