V07E320P - UltraMOV Series

The UltraMOV Metal Oxide Varistor Series is designed for applications reqiring high peak surge current ratings and high energy absorption capability. UltraMOV varistors are primarily intended for use in AC Line Voltage applications such as Transient Voltage Surge Suppressors (TVSS), Uninterruptable Power Supplies (UPS), AC Power Taps, AC Power Meters, or other products that require voltage clamping of high transient surge currents from sources such as lightning, inductive load switching, or capacitor bank switching.
  • These devices are produced in radial lead package sizes of 7, 10, 14, and 20mm and offered in a variety of lead forms.
  • UltraMOVs are manufactured with recognized epoxy encapsulation and are rated for ambient temperatures up to 85°C with no derating.
  • This Series is LASER-branded and is supplied in bulk, ammo pack (fan-fold), or tape and reel packaging.

AN9312 Suppression of Transients in an Automotive Environment

This application note discusses suppression of transients in the automotive environment. The circuit designer must ensure reliable circuit operation in this severe transient environment. The transients on the automobile power supply range from the severe, high energy, transients generated by the alternator/regulator system to the low-level "noise" generated by the ignition system and various accessories.

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.

pdf icon Combining GDTs and MOVs for Surge Protection of AC Power Lines Application Note

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.
