JVR14N471K87YU4 – JOYIN

The JVR14N471K87YU4, manufactured by JOYIN, is a metal oxide varistor (MOV) designed for transient voltage suppression. This component is specified as a 14N471K type, indicating a nominal varistor voltage of 470V at a test current of 1mA, with a tolerance of ±10% (denoted by the “K”). The “14” in the part number designates a disc diameter of approximately 14mm. The device is rated for a maximum continuous operating voltage of 300V AC (RMS) or 385V DC. The 80J rating signifies the varistor’s energy handling capability; it can absorb up to 80 joules of energy from transient events. The device is intended to protect sensitive electronic circuits from voltage surges caused by lightning, inductive load switching, and electrostatic discharge.
