Bourns Metal Oxide Varistors
Bourns Metal Oxide Varistors (MOVs) are engineered to limit voltage spikes and safeguard electronic circuits from transient surges. These MOVs are available in 7mm, 10mm, 14mm and 20mm radial leaded formats and provide high energy absorption, strong surge current handling, and rapid response. The MOVs offer voltage ratings from 18V to 1800V and power ratings from 0.25W to 1W. These are typically used in power supplies, telecommunications equipment, and household appliances.
