The Littelfuse LV UltraMOV® Varistor Series provides an ideal circuit protection solution for DC voltage applications. 

The maximum peak surge current rating can reach up to 10kA (8/20μs pulse) to protect against the damage from high peak surge current induced by indirect lightning strike interference, system switching transients, and abnormal fast transients from the power source. 

Available in five model sizes: 5mm, 7mm, 10mm, 14mm, and 20mm, these device feature a wide voltage range from 14V to 125V. 

## **Features & Benefits** 

- Breakthrough in low voltage ■ High operating temperature varistor design provides range up to 125ºC high peak (up to 10KA) (phenolic coating option) surge current rating 

- 5 model sizes available: 

- ■ Reduced footprint and volume 5, 7, 10, 14, and 20mm required for surge protection 

- 10mm, 14mm and 20mm 

- ■ Wide operating voltage range devices are UL Recognized VM(AC)RMS 11V to 95V and TUV certified with 800V and V M(DC) 14V to 125V isolation voltage rating. 

- Lead–free, Halogen-Free and RoHS compliant 

## **Applications** 

   - Automation control systems 

- LED lights 

- Cordless phones 

   - Industrial control contact relays 

- Audio and video devices 

   - Surge protection device 

- Mobile phone chargers 

   - Telecom power systems 

- Security systems 

   - Wireless base stations 

- Fire alarm systems 

## **Notes:** 

1. 10mm, 14mm and 20mm phenolic coated parts are UL Recognized for the US and Canada. 

2. All epoxy coated parts (in all sizes) are UL Recognized for the US. 

3. 10mm, 14mm and 20mm phenolic coated parts only.

**Note:** If pulse ratings are exceeded, a shift of VN(DC)(at specified current) of more then +/-10% could result. This published specifications, but does not prevent the device from continuing to function, and to provide ample type of shift, which normally results in a decrease of VN(DC), may result in the device not meeting the original protection.
