Littelfuse SM10 Surface Mount Varistors
Littelfuse SM10 Series Surface Mount Varistors are Metal Oxide Varistors (MOV) that have ultra-high surge current handling capability. These varistors are specifically designed for primary circuit transient voltage surge protection and have a high maximum operating temperature of 125°C. The varistors are constructed with a MOV disc and tin-plated terminals within a polymer molded package, with fully qualified lead-free soldering. SM10 series varistors are RoHS compliant, lead-free, and halogen-free, and find application in general electronics and electrical products.
