10KA Gas Discharge Tubes GDT SMD5050 Series Surge Arrester Protector 75V 470V Arrestor Circuit Protection Components
Description of 10KA Gas Discharge Tubes GDT SMD5050
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 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.
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.
