The UltraMOV Series of Metal Oxide Varistors is designed

for applications requiring high peak surge current ratings and

high energy absorption capability. UltraMOVs 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

C with no derating. This Series is LASER-branded and is

supplied in bulk, ammo pack (fan-fold), or tape and reel

packaging. The UltraMOV series also incorporates a new,

easy-to-understand nomenclature.

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.

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.
