HB34 Series - High Energy Industrial Varistor Series

The HB34 Series of transient surge suppressors are industrial high-energy Metal-Oxide Varistors (MOVs).

They are designed to proide surge suppression in the AC mains outdoor and service entrance environment (distribution panels) of buildings.
HB34 applications also include industrial heavy motors, controls, and power supplies such as used in the oil-drilling, mining, and transportation fields, including HVAC and motor/generator applications.
The HB34 Series provides rigid terminals for through-hole solder mounting on printed circuit boards, thereby eliminating the need for screw mounting.

	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. an9311.pdf (209 K)
	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. Littelfuse_app-note_an9767.pdf (2,930 K)
	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. an9768.pdf (279 K)
