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
V
used in automotive, motor-control, telecommunication, and
military applications.
See RA Series Device Ratings and Specifications Table for
part number and brand information.
