Metal Oxide Varistors (MOV)
Bourns® MOV product portfolio offers 7 mm and 10 mm radial leaded varistor devices which protect against overvoltage transients such as lightning, power contact and power induction. The metal oxide varistors offer a choice of varistor voltages from 18 V to 820 V and Vrms voltages from 11 V to 510 V. The devices have high current handling, high energy absorption capability and fast response times to protect against transient faults up to rated limits.
