RA Series Data Sheet

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.

	AN9311 The ABCs of MOVs The material in this application guide has been arranged in 3 parts for easy reference; Section A provides general guidelines on what types of MOV products are best suited for particular environments. Section B explains what Metal Oxide Varistors are and the basic function they perform. And section C helps clarify important information about MOVs for the design engineer, and answers questions that are asked most often.
	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.
	AN9773 Varistor Testing This application note details the common tests of varistor parameters and describes suitable test methods using simplified test circuits. All tests are performed at 25° C, unless otherwise specified. The test circuits and methods given are intended as a general guide. Since the tests frequently entail high voltages and currents, users must exercise appropriate safety precautions.
	EC638 Littelfuse Varistor Design Examples This application note is a guide for selecting a varistor by describing common application examples, and illustrating the solution process to determine the appropriate varistor. The note also describes series/parallel connection rules.
	EC640 Combining GDTs and MOVs for Surge Protection of AC Lines This application note illustrates how to design high performance, cost-effective surge protection for equipment connected to AC power lines. The role of gas discharge tube (GDT) surge arresters specifically designed for AC power line protection is also be discussed.
	AN9767 Littelfuse Varistors Basic Properties Terminology and Theory This application note describes the basic properties of varistors. Varistors are voltage dependent, nonlinear devices which have an electrical behavior similar to back-to-back zener diodes. The symmetrical, sharp breakdown characteristics enable the varistor to provide excellent transient suppression performance.
