Product Description

 

3R-3SS SMD Tape 2KA 90V-470V GDT Gas Discharge Tube High Insulation Resistance For Broadband Equipment

 

Description of 3R-3SS SMD Tape 2KA 90V-470V GDT Gas Discharge Tube

 

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. 3R-3SS Gas Discharge Tubes (GDT) series has a surge rating of 2kA, 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.


3R-3SS 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.
