Joyin Metal Oxide Varistors
Brand: JoyinA comprehensive range of voltage dependent metal oxide varistors 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
- UL approved
