Surface mount MOV

14 April 2010 Circuit & System Protection

Littelfuse recently introduced the SM7 series surface mount MOV for over-voltage protection and transient suppression. It is designed for continuous operation across AC power lines and is highly suitable for AC power meters, detectors and sensors, plug-in cards and remote controllers. It features a wide operating voltage up to 510 V a.c., and is lead-free and RoHS compliant, as well as Halogen-free.

The SM7 is a plastic-encapsulated surface mount MOV in a nylon moulded package with tin-plated terminal which is fully qualified in lead-free and SnPb soldering and available for both reflow and wave soldering process. It is based on a radial 7 mm internal varistor element. The part’s operating ambient temperature is as high as 85°C with peak pulse current of 1200 A. It is UL recognised and has UL agency approval under UL 1449 edition 3.
