Voltage Insulation 10kA 75V-1000V 2RB-8S Gas Discharge Tube 2R GDT Lead-free for XDSL Equipment 8.3mmx6mm
Description of 10kA 75V-1000V 2RB-8S Gas Discharge Tube 2R GDT
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. 2RB-8S 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.
2RB-8S 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.
