  LV UltraMOV Varistors from Littelfuse Offer Higher Surge Current Ratings in
  Smaller Disc Sizes

  Designed to protect lower voltage DC applications against high peak surges

CHICAGO -- February 25, 2013

Littelfuse, Inc., the global leader in circuit protection, has introduced the
LV UltraMOV™ Series of low voltage, high surge current, radial leaded
varistors. They provide an ideal circuit protection solution for lower DC
voltage applications by offering higher surge ratings than ever before
available in such small disc sizes. Their high peak surge current rating
provides superior protection against high peak surges, including indirect
lightning strike interference, system switching transients and abnormal fast
transients from the power source. Typical applications of these devices
include LED lighting drivers, cordless phones, wireless base stations, audio
devices, mobile phone chargers, security systems, fire alarm systems and
automation control systems (PLCs).

“The LV UltraMOV Series is unrivaled in the industry in terms of its surge
current rating, energy handling capabilities, and ability to withstand
multiple strikes; no competitive product comes close,” said Johnny Chang,
Product Manager, LV UltraMOV Series Varistor product line. “For example, a
10mm LV UltraMOV Series Varistor offers a maximum surge current rating that’s
four times higher than a standard MOV of the same size.”

The LV UltraMOV Series Varistors offer these key features and benefits:


  *Breakthrough in low voltage varistor design provides high peak surge
    current rating
  *Reduced footprint and volume required for surge protection
  *High energy absorption capability
  *High resistance to temperature cycling
  *Optional phenolic coating
  *Lead-free, halogen-free, and RoHS compliant


  *Increased long-term reliability due to the ability to handle higher surges
    over the end product's lifetime
  *More board space is available for higher value functional components
  *Lower weight and cost for end product from use of a smaller disc
  *Higher surge handling density in critical surge protection device module
  *Higher operating temperature range—up to 125°C
  *Environmentally friendly product

The LV UltraMOV Series Varistors are available in bulk, tape and reel, and
ammo packaging. Samples are available now for bulk orders; sample requests can
be placed through authorized Littelfuse distributors worldwide. For a listing
