3RA-5S GDT 5KA 3 Poles Gas Discharge Tube 400V 420V 470V 600V 800V Surface Mount Assembly
Description of 3RA-5S GDT 5KA 3 Poles Gas Discharge Tube 400V 420V 470V 600V 800V Surface Mount Assembly
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. 3RA-5S Gas Discharge Tubes (GDT) series has a surge rating of 5kA, 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.
3RA-5S 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.
