ULTRAMOV™ Series
Specifications are subject to change without notice.
Please refer to www.littelfuse.com/series/tmov.html for current information.
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 as Transient 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.
Features
• Lead–free, Halogen-Free
and RoHS compliant.
• High peak surge
current rating (ITM) up
to 10kA, single 8 x
20 pulse, (20mm)
• Standard operating
voltage range compatible
with common AC
line voltages (130
VAC to 625 VAC)
• Characterized for
maximum standby
current (Leakage)
• Custom voltage
types available
• Standard lead form and
lead space options

UltraMOV™ Series Ratings & Specifications (Continued...)
NOTE:
1. Average power dissipation of transients should not exceed 0.25W, 0.4W, 0.6W and 1.0W for 7mm, 10mm, 14mm, and 20mm model sizes, respectively.
Should transients occur in rapid succession, the average
power dissipation is the energy (watt-seconds) per pulse
times the number of pulses per second. The power so
developed must be within the specifications shown
on the Device Ratings and Specifications Table for the
specific device. Furthermore, the operating values
need to be derated at high temperatures as shown in
above. Because varistors can only dissipate a relatively
small amount of average power they are, therefore,
not suitable for repetitive applications that involve
substantial amounts of average power dissipation.
