## ~~**Description** LT~~ 

The Littelfuse AUMOV[®] Varistor Series of low voltage, high surge current, radial leaded varistors provides an ideal circuit protection for load dump, jump start voltage transient conditions specifically for automotive applications. 

The maximum peak surge current rating is rated up to 5kA (8/20 μs pulse) to protect sensitive infotainment systems from voltage transients.  This AEC-Q200 (Table 10) qualified series is available in five disc sizes: 5mm, 7mm, 10mm, 14mm and 20mm; it features a wide VDC voltage range from 

16V to 825V.

**Note:** 

**1.** Average power dissipation of transients not to exceed 0.2W, 0.25W, 0.4W, 0.6W or 1W for model sizes 5mm, 7mm, 10mm, 14mm and 20mm, respectively. 

**2.** *Energy rating (auto load dump) for impulse duration of 40ms minimum to one half of peak current, 60sec interval ISO7637-2 pulse 5a and ISO16750-2 Table 5A. 

**3.** The shift of Vnom ( Varistor Volatge ) may be to +/-15% for Load dump or Jump Start test. 

**4.** The ratings and specifications of Silicone coated options are the same as the Phenolic coating, except the isolation voltage capability (Hi-Pot Encapsulation) is 2500V.
