METAL OXIDE VARISTORS TNR
TM
Compliant
RoHS
?FEATURES
@Excellent
clamping voltage characteristic and fast response time (<50 ns) when subjected to impulse surges.
@No
follow current.
@Any
voltage rating within a V1mA range from 200 to 1,100V available. (V1mA : varistor voltage.)
@Bilateral
and symmetrical V- I characteristics curve.
@The
TNR can, therefore, be used both in AC and DC circuits, for protection of either positive or negative transients.
@Large
withstanding peak current 8,000 to 25,000A(8/20Ms).
?APPLICATIONS
@Protection
of semiconductors such as transistors, diodes, ICs, thyristors, triacs, etc.
@Protection
of various equipment including:
*Broadcasting, communications equipment.
*Traffic and railway signal systems.
*Automatic control devices for power distribution.
*Waterworks.
*Home entertainment equipment.
@Surge
absorption of relays and electromagnetic valves.
@Absorption
of surges generated within equipment such as TVs.
