Varistors

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.

EC608 Considerations for Selecting Littelfuse MOVs and Fuses for Industrial Motor Applications

This application note discusses the first level considerations for applying both Littelfuse Industrial AC Line Metal Oxide Varistors and associated AC line Fuses with a motor protection example.

EC637 Recommendations for Soldering Terminal Leads to MOV Varistor Discs

This technical brief presents the CA and NA series of MOV varistor discs and discusses how they are specifically designed for custom assembly and packaging. It outlines how to take advantage of the excellent performance and reliability of Littelfuse varistor technology by choosing the correct materials and processes when soldering terminal leads to the disc.
