 varistors

Circuit protection specialist Littelfuse has recently debut its LV UltraMOV series of radial-leaded metal-oxide varistors. Used for circuit protection in low-voltage applications, the LV UltraMOV varistors handle maximum peak surge currents as high as 8 kA (8/20-µs pulse), yet reside in small disc packages, reducing the footprint and volume required for surge protection.

The MOVs are available in 5mm, 7mm, 10mm, 14mm, and 20mm sizes with epoxy or phenolic coatings. According to the manufacturer, a 10mm LV UltraMOV series varistor offers a maximum surge current rating that is four times higher than a standard MOV of the same size.

Devices in the series operate over a wide voltage range of 11 VAC to 40 VAC and 14 VDC to 56 VDC. They protect against indirect lightning-strike interference, system switching transients, and abnormal fast transients from the power source. Typical applications 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 varistors are available in bulk, tape and reel, and ammo packaging. Samples are available now for bulk orders. Sample requests can be placed through authorised Littelfuse distributors worldwide.

Datasheet for the LV UltraMOV series varistors can be accessed here.
