3RB-5SS 5mmX5mmX7.5mm Gas Discharge Tube 90 Volt Gas Tube Arrester For Circuit Protection PCB Board

3RB-5SS 5mmX5mmX7.5mm Gas Discharge Tube 90 Volt Gas Tube Arrester For Circuit Protection PCB Board

Description of 3RB-5SS 5mmX5mmX7.5mm 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. 3RB-5SS Gas Discharge Tubes (GDT) series has a surge rating of 10kA, 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.

3RB-5SS 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.
