Metal-Oxide Varistors (MOVs) Low Profile / Application Specific Varistors > RA Series RA Varistor Series RoHS Description The RA Series transient surge suppressors are varistors (MOVs) supplied in a low-profile box that features a precise seating plane to increase mechanical stability for secure circuit-board mounting. This feature makes these devices suitable for industrial applications critical to vibration. Their construction permits operation up to 125ºC (ambient) without derating. The RA Series are available in voltage ratings up to 275V VM(AC)RMS, and energy levels up to 140J. These varistors are used in automotive, motor-control, telecommunication, and military applications.

The power so developed must be within the specifications shown on the Device Ratings and Specifications table for the specific device. Furthermore, the operating values need to be derated at high temperatures as shown above. Because varistors can only dissipate a relatively small amount of average power they are, therefore, not suitable for repetitive applications that involve substantial amounts of average power dissipation. © 2015 Littelfuse, Inc.
