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.

AN9768 Transient Suppression Devices and Principles

This application note discusses the two major categories of transient suppressors: a) those that attenuate transients, thus preventing their propagation into the sensitive circuit; and b) those that divert transients away from sensitive loads and so limit the residual voltages.

AN9769 An Overview of Electromagnetic and Lightning Induced Voltage Transients

This application note is an overview of the sources and nature of various transient overvoltages, and the problems that may result.
