4532 Surface Mount Gas Discharge Tube GDT SMD230XM 1812 230V 3KA
750V 0.5pF
I Gas Discharge Tube Description
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
and Ampfort offers products that function at
20KA,40KA,50KA,60KA,100KA&150KA.The breakdown voltages of the
devices have a wide range (up to 20% tolerance).Major applications
are high frequency telecommunication lines,stations, security
systems,HID and high quality Surge Protection Devices (SPD).
