Surface Mount Metal Oxide Varistor
SM10 Series
RoHS Pb
Description
Littelfuse SM10 Varistor Series is the first surface-mount Metal
Oxide Varistor (MOV) with ultra-high surge current handling
capability, specifically designed for primary circuit transient voltage
surge protection. The SM10 Varistor Series is constructed with an
MOV disc and tin-plated terminals within a polymer molded
package, which is fully qualified in lead-free soldering and
compatible with both reflow and wave soldering process.
