Product Description

 

3R-3 Ceramics Surge Protection 3 Electrode Gas Discharge Tubes GDT For High Bandwidth Applications

 

Description of 3R-3 Ceramics Surge Protection 3 Electrode Gas Discharge Tubes GDT For High Bandwidth Applications

 

Gas discharge tubes (GDT) use noble gasses enclosed in ceramic tubes to provide an alternate circuit path for voltagespikes. The ceramic envelope and with nickel connectors allow for high loads. 3R-3S 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-3S 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.
