Varistors

Varistors provide transient voltage surge suppression in consumer electronics, household appliances, telecom equipment, and computers. The overvoltage protection devices shield semiconductors and other components from damage due to lightning strikes, and electrostatic discharges. Littelfuse produces metal oxide varistors (MOVs) in surface mount, thermally protected, and radial leaded configurations. In addition to AUMOV^®, UltraMOV^®, and TMOV^® devices, we design specialty varistors to customers’ specifications.
