SMD5050-B GDT 5KA SMD 5050 800V Surface Mount Gas Discharge Tube Ceramic Surge Protector Arrester
Description of SMD5050-B GDT 5KA SMD 5050 Surface Mount 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. SMD5050 Gas Discharge Tubes (GDT) series has a surge rating of 5kA, 8/20μs.Offered in a Squared Surfac 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.
SMD5050 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.
