Description

Reviews

Varistors are used to protect electronic equipment from overvoltages by absorbing energy. The current-voltage characteristic of a varistor is similar to that of a zener diode. To select a varistor, use the indicator of absorbed energy J and the maximum voltage Umax (AC voltage is indicated)
Varistor classification voltage 390 V, Maximum peak current 100 A
