Littelfuse introduces the SM10 series varistors, a breakthrough in surge protection for automotive and electronics

     Littelfuse announced the SM10 varistor family, a revolutionary metal-oxide varistor (MOV) designed to provide superior transient surge protection for automotive electronics, electric vehicles (EVs) and a wide range of other applications. This latest product is the first surface mount MOV device compliant with the AEC-Q200 automotive standard, capable of operating at high temperatures and offering ultra-high surge current handling capabilities in a compact package.

     "The SM10 series varistors have ultra-high surge handling capabilities to effectively protect electronic circuits from multiple transient voltage surges." "This AEC-Q200 compliant product enables end products to operate in harsh environments and extend their service life," said Johnny Chang, Director of product management at Littelfuse.

     Amy Chu, global Product Manager at Littelfuse, added: "The vertical surface-mount SM10 series varistors enable electronic designers to achieve primary side circuit surge protection in accordance with the 'SMT component only principle'. This compact product replaces through-hole devices for fully automated and SMT PCB assembly processes."

     Compared to existing solutions, the SM10 series offers unmatched performance with high operating temperatures, repeated surge protection and compact size. Combined, these properties provide an attractive option for the automotive, appliance and building automation industries that require reliable, high-surge varistors.
