LITTELFUSE UltraMOV User Manual
UltraMOV™Varistor Series
®
V
DE
®
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 85
o
C 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 and RoHS compliant option available. Please see the
device and ratings specifications table for more information.
• 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 (130VAC to 625VAC)
• Characterized for Maximum Standby Current (Leakage)
• Custom Voltage Types Available
• Standard Lead Form and Lead Space Options
AGENCY APPRO VALS: Recognized under the components program of
Underwriters Laboratories. Certified by CSA, VDE and CECC.VDE certification of Lead-free and RoHS compliant parts pending.
AGENCY FILE NUMBERS: UL E75961, CSA LR91788,
VDE 116895E, CECC 42201-006.

Power Dissipation Ratings
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 Figure 1. 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.
