Metal-Oxide Varistors (MOVs)
Radial Lead Varistors > 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 as Surge Protection Device (SPD), 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. UltraMOV® varistor 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
• High operating
temperature range up to
125°C (phenolic coating
option). 10mm, 14mm
and 20mm devices are
UL Recognized and
TUV certified with 800V
isolation voltage rating

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
Current Energy and Power Dissipation Ratings

at high temperatures as shown above. Because varistors
only dissipate a relatively small amount of average power
they are not suitable for repetitive applications that involve
substantial amounts of average power dissipation.

Metal-Oxide Varistors (MOVs)
Radial Lead Varistors > UltraMOV® Varistor Series
Phenolic Coating Option -- UltraMOV® Varistor Series for Hi-Temperature Operating Conditions:
• Phenolic Coated UltraMOV® Varistor Series devices are available
with improved maximum operating temperature 125°C.
• These devices also have improved temperature cycling performance capability.
• Ratings and Specifications are as per standard UltraMOV® Series
except Hi–Pot Encapsulation (Isolation Voltage Capability) = 800V.
• Phenolic Coating is HALOGEN FREE. To order: change 'E' (Epoxy
coating) in part number to 'P' (Phenolic coating; e.g. V20P230)
• See Part Numbering System section of this series for more information.
• Contact factory for further details.
