Description of 2RD-8S Gas Discharge Tubes 2R 20kA GDT
Gas discharge tubes (GDT) use noble gasses enclosed in ceramic tubes to provide an alternate circuit path for voltage spikes. The ceramic envelope and with nickel connectors allow for high loads. 2RD-8S Gas Discharge Tubes (GDT) series has a surge rating of 20kA, 8/20μs.Offered in a Squared Surface Mount package, which helps to make pick and place on PCB process easier.
This
GDT
series
is
perfectly
suited
for
broadband
equipment
applications.
The
GDT’s
low
off-state
capacitance
is
compatible
with
high
bandwidth
applications
and
this
capacitance
loading
value
does
not
vary
if
the
voltage
across
the
GDT
changes.
2RD-8S
Gas
Discharge
Tube
(GDT)
series
are
specifically
designed
for
protection
of
electrical,
multimedia,
and
communication
equipment
against
over
voltage
transients
in
surface
mount
assembly
applications.
