2R-5SS Series 75V-800V 1pF Surge Protector Telecom Line Lightning
Arrester Ceramic Gas Discharge Tube GDT
Decription
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.
2R-5SS 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.
