MOV-20D821K Metal Oxide Varistor Thakor (VCRR)

Product Description

MOV-20D821KMetal Oxide Varistor (Thakor VCRR)

ProductDescription

The MOV-20D821K is a metal oxide varistor(MOV) manufactured by Thakor (VCRR). It is designed to protect sensitiveelectronic circuits and components from transient voltage surges, includingthose caused by lightning, power line disturbances, and switching transients.It achieves this by clamping high transient voltages and preventing them fromdamaging downstream components.
