Varistor Products

High Surge Current, Radial Lead

RoHS

UltraMOV

™

Varistor Series

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

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

NEW LEAD-FREE AND

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

PERCENT OF RATED VALUE

Should transients occur in rapid succession, the average power dissipa-

tion 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.
