The R-C Snubber is intended to suppress the “inductive kick back” from motors, solenoids, relay coils, pumps or any device that creates an electro-magnetic collapsing field. High energy noise spikes are generated whenever current is interrupted through an inductive load connected to a switching circuit. These electro-magnetic noise spikes (EMI) may interfere with electronics equipment causing erratic operation, CPU failure and may also accelerate relay contact wear. Applied across an inductive load, the R-C snubber suppresses the electrical noise spikes to electronics and extends contact life on mechanical relays.
