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
 
Technical Specifications :
• Material :  Zinc Oxide (ZnO)
• Storage Temperature :  -40...+125°C
• Operating Temperature, Max. :  +85°C
• Working Surface Temperature, Max. :  +115°C
• Response Time, Max. :  25ns
• Voltage/Temperature Coefficient :  -0,05%/°C
• Insulation Resistance 500V :  >1000MW

• URMS [V AC] : 300
