SM7 Surface-Mount Varistors

Littelfuse SM7 Surface-Mount Metal Oxide Varistors (MOV) are designed to be operated continuously across AC power lines. These transient voltage surge suppressors come in a molded PPS-material package with a tin-plated lead frame for soldering to board. Littelfuse SM7 MOVs are based on a radial 7mm internal varistor element with characteristics similar to the Littelfuse LA/ZA series.
