Voltage dependent metal oxide varistor from Joyin for suppressing mains borne transients, spikes etc.
Epoxy coated disc construction with radial leads
When the protected equipment or circuit encounters a high voltage spike the varistor charges impedance from its normal high standby value to a very low conducting value thus clamping the transient voltage to a protective level
Varistor absorbs the unwanted high voltage pulse protecting voltage sensitive components against damage
