Description
The Littelfuse SM7 Series is a plastic-encapsulated
surface-mount metal oxide varistor (MOV) transient
voltage surge suppressor that is designed to be
operated continuously across AC power lines.
The series comprises a Nylon molded package with
tin plated lead frame for soldering to board. The
surface mount SM7 Series is based on radial 7mm
internal varistor element with similar characteristics
to the Littelfuse LA / ZA series of varistor.
