JVR20N471K - Varistor 300VAC 470VDC 6500A

Features
• Used as voltage-dependent resistors (VDR's) to protect electronic devices
• They protect against overload build-up and protect valuable equipment from power surge damage
• Surge voltages are absorbed in the varistor

Selection Criteria
• The maximum operating voltage must be lower than the varistor voltage
• The capacity of the varistor (energy absorption) should match the energy content of the varistor
