Littelfuse SM10 Series Surface-Mount Varistors
Littelfuse SM10 Series High Surge Surface-Mount Metal Oxide Varistors (MOVs) are specifically designed for primary circuit transient voltage surge protection. The MOV disc and tin-plated terminals of the SM10 varistors are housed in polymer-molded packaging that is completely qualified for lead-free soldering and compatible with both reflow and wave soldering techniques. SM10 varistors are environment-friendly, meet automotive-grade standards, and provide extended product reliability and lifespan. These varistors feature an operating temperature range from -40°C to +125°C and an insulation resistance of ≥100MΩ. Typical applications include electricity power storage and general electronics.
