I am trying to make a coil suppressor to restrict any voltage above say 130v. It is a simple VDR RC circuit. I am using a resistance of 47ohm, 250v and a capacitor of .1nF 250v a VDR of 130v. But the circuit is not working as expected. Is it because of the voltage spec of resistance and capacitor? Should it not restrict any voltage above 130v. But when am testing it, voltages above 130v are passing through it.
