CHICAGO, Illinois, August 3, 2009 – Littelfuse (NASDAQ: LFUS) today announced the launch of Ultra MOV^TM 25S Varistor Series for applications requiring high peak surge current rating and high energy absorption capability. The new varistor series withstands peak surge current up to 22 kA at single 8/20 µs pulse which is the highest in the market. It can protect against lightning striking interference and abnormal power source from incoming power lines.

The device in 25 mm X 25 mm square form in a radial lead package with straight leads is a new concept of circuit protection for high peak surge applications such as Surge Protective Devices (SPD), Uninterruptable Power Supplies (UPS), Transient Voltage Surge Suppression (TVSS) modular, non-modular TVSS, DIN rail TVSS, AC power taps, AC power meters, measuring and controlling systems, etc.

Ultra MOV^TM 25S Varistor Series is characterized as having very fast response time with a wide range of operation voltages ranging from 115 VAC to 750 VAC. Phenolic coated option is available which makes possible operating temperature up to 125 °C and thus, can even prevent fire.
