  1. Hello
    We designed this Snubber Circuit with this varistor in parallel but we have a problem in a small load. Even when the relay is disconnected, a small current is flowing. For example, when connecting a phone charger, the phone screen keeps turning on and off.
    The varistor is Hongzhi Elec 7D471K
    The resistor is 2.2 ±5% 1W ±350ppm/°C Axial,3.3x9.2mm Carbon
    The capacitor is 100nF ±10% 275VAC 10 Through Hole,P=10mm Suppression Capacitors

    I think the problem is with the capacitor and maybe I need a smaller one to increase the impedance and limit the current flow or schematic problem.
