2R-4S 75V to 800V 3KA 1pF Lightning Protector Electrode Surge
Arrester GDT Gas Discharge Tubes
Description
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.
2R-4S Gas Discharge Tubes (GDT) series has a surge rating of 3kA,
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.
2R-4S 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.
