Description

General part information

V39RA8X2749 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 125°C (ambient) without derating. The RA series are available in voltage ratings up to 275V V M(AC)RMS and energy levels up to 140J. These varistors are used in automotive, motor control, telecommunication, and military applications.
