Metal Oxide Varistors

What are they?Metal Oxide Varistors, more commonly known as MOVs are devices that provide excellent transient voltage suppression. They are a type of non-linear device that feature similar characteristics to Zener diodes. They are used to protect vulnerable electronic circuits and components from overvoltage conditions that can cause damage. Any potentially destructive overvoltage energy is dissipated as heat.Construction:Metal oxide varistors are typically constructed from zinc oxide and combined with small additions of other metal oxides such as cobalt, magnese or bismuth. These materials are sintered into ceramic casings during manufacture. Although MOVs are available in different formats, they are most commonly radial leaded discs.Applications: Suppression of lightning and other high levels of transient energy Low voltage power supplies in DC circuits Low voltage power supply in automotive applications Protection from internal transients within capacitor discharges, relay switching and inductive load switching
