VARISTOR JVR05N390K
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
