SM20 Series 20 mm SMD Varistors
Littelfuse latest development in overvoltage circuit protection and transient suppression
The Littelfuse SM20 series devices are surface-mount metal oxide varistors that are used in applications requiring hi-energy and transient current capability. The AC rated parts are designed to operate continuously across AC power lines. The DC rated parts are suitable for automotive applications, and the series comprises a Nylon molded package with folded tin plated metal leads for soldering to a PCB. The SM20 series is based on a radial 20 mm internal varistor element with similar characteristics to the Littelfuse LA/ZA series of varistors.
