Varistor Products  
Radial Lead Varistors > UltraMOVTM Series  
RoHS  
UltraMOV™ Varistor Series  
Description  
The UltraMOV™ Metal Oxide Varistor Series is designed  
for applications requiring high peak surge current ratings  
and high energy absorption capability. UltraMOV™  
varistors are primarily intended for use in AC Line Voltage  
applications such asTransient Voltage Surge Suppressors  
(TVSS), Uninterruptable Power Supplies (UPS), AC Power  
Taps, AC Power Meters, or other products that require  
voltage clamping of high transient surge currents from  
sources such as lightning, inductive load switching, or  
capacitor bank switching.  
These devices are produced in radial lead package sizes of  
7,10,14 and 20mm and offered in a variety of lead forms.  
UltraMOVs™ are manufactured with recognized epoxy  
encapsulation and are rated for ambient temperatures up  
to 85ºC with no derating. This Series is LASER-branded and  
is supplied in bulk, ammo pack (fan-fold), or tape and reel  
packaging.
