Metal-Oxide Varistors (MOVs) 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 125C (ambient) without derating. The RA Series are available in voltage ratings up to 275V V , and energy levels up to 140J. These varistors are M(AC)RMS used in automotive, motor-control, telecommunication, and military applications. Agency Approvals See RA Series Device Ratings and Specifications Table for part number and brand information.
