Varistor Terminology
Varistor Voltage : Vnom
Traffic Signal Control
Vending Machine
Clamping Voltage : Vc
Maximum terminal voltage (peak voltage across the varistor)
measured with an applied 8/20㎲ impulse of a given peak
current.
Varistor peak terminal voltage measured with a specified
current applied The DC current applied is 1mA normally.
