S20K275 Description

Short technical summary and product information.

The S20K275 is a metal oxide varistor (MOV) manufactured by S+M, designed for robust circuit protection applications. This component features a maximum AC applied voltage rating of 275V RMS and a nominal DC varistor voltage of 430V. It can handle a peak current of 6.5kA and has a clamping voltage of 710V at 100A.

 

With a transient energy rating of 140 Joules and a response time of 15 nanoseconds, the S20K275 is suitable for absorbing voltage transients. The varistor element is round and leaded, with a coating of flame-retardant epoxy resin compliant with UL 94 V-0. The terminals are made of tinned copper wire, facilitating through-hole mounting.

 

This varistor is part of the SuperioR Series, known for its high-energy capabilities and very high surge current ratings. Its construction and specifications make it a reliable choice for protecting electronic equipment from voltage spikes and surges.
