Zinc Oxide Varistor
1.2 HEL VARISTORS ELECTRICAL CHARACTERISTICS
The maximum energy within the varistors voltage
change of ±10% when one impulse of 2ms or
10/1000μS is applied.
For the 2mS waveform
J=2*Ip* Vc*10-3
For the 10/1000μS waveform
Energy
J=1391*Ip* Vc*10-6
Where J -- Energy absorbed in joules.
Ip -- Maximum let-through current in
amps.
Vc-- Measured clamping voltage in volts.
ΔV1mA /V1mA10%.
