LV UltraMOV Varistors Offer Higher Surge Current Ratings in Smaller 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:

Features
• 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

Benefits
• 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 solutions
• Higher operating temperature range—up to 125°C
• Environmentally friendly product

Availability
The LV UltraMOV Series Varistors are available in bulk, tape and reel, and ammo packaging.
