Varistor Series
Description
RoHS
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.

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.
Current Energy and 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
Figure 1A - Power Derating for Epoxy Coated
100
device. The operating values of a MOV need to be derated
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.
