* working surface temperature, max.: +115°C
* response time, max.: 25ns
* voltage/temperature coefficient: -0.05%/°C
* insulation resistance 500V: >1000MΩ
* 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.
