Low Voltage SMD 1812 Multilayer Chip Metal Oxide Varistors MVR1812-390H 39V 800A 2500pF 3.1J 4532 Metric Surface Mount

 

 

Description

 

The MVR Series of low voltage varistors is designed to protect sensitive electronics devices against high voltage surges in the low voltage region. They offer excellent transient energy absorption due to improved energy volume distribution and power dissipation. Low voltage varistors cover wide DC operating voltage range from 3V to 170V. The MVR Series is the same except for higher operating temperatures up to 150ºC. MVR varistors are typically applied to protect components at the circuit board level.
