Document: SCD 25484

Status: Released

Rev. A June 30, 2003

GENERAL DESCRIPTION

The ROV20-XXX (Radial-leaded Metal

Oxide Varistor)

products are 20mm radial leaded varistor devices

suitable for protection of overvoltage transients.

ROV devices can provide protection for a wide variety

of power systems against overvoltage faults such as

lightning, power contact and power induction. Suitable

for a broad range of applications including, but not

limited to security, power supplies, surge strips, etc.,

the ROV device helps to protect valuable equipment

from potential power surge damage by clamping high

energy, short duration impulses. The ROV devices

have high current handling and energy absorption

capability and fast response times to help protect

against transient faults.
