Description
The Littelfuse SH Gas Discharge Tubes (GDT) series provides high
levels of protection against fast rising transients caused by
lightning disturbances. It has a surge rating of 5kA, 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.
The Littelfuse SH 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.
