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.

TYPICAL APPLICATION SCHEMATIC
Protected
device
*
*In some applications, a polymeric PTC device such as a Tyco Electronics PolySwitch device may be used instead of a
fuse to provide a preferred solution.
MATERIALS INFORMATION
RoHS Compliant ELV Compliant
*After May 1, 2005 all ROV devices will be produced as RoHS compliant devices.
