Varistor Products  
Low Profile / Application Specific Varistors > RA Series  
RoHS  
RA Varistor Series  
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.
