Low Profile
RA Varistor Series
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.
See RA Series Device Ratings and Specifications table for part number
and brand information.
