Low Capacitance 4.5mm*3.2mm SMD 230XM Gas Discharge Tube For
Telecommunications
SMD
230XM.pdf
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 Ruilon 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).
Selection principle
(1) The DC discharge voltage of the gas discharge tube must be
higher than the maximum voltage during normal operation of the
line, so as not to affect the normal operation of the line.
(2) The pulse discharge voltage of the gas discharge tube must be
lower than the highest instantaneous voltage value that the line
can withstand, so as to ensure that the gas discharge tube can
respond faster than the line in the event of instantaneous
overvoltage, and limit the overvoltage to a safe value in advance .
(3) The holding voltage of the gas discharge tube should be as high
as possible. Once the overvoltage disappears, the gas discharge
tube can be extinguished in time without affecting the normal
operation of the line.
(4) The ground wire should be as short as possible and thick enough
to facilitate the discharge of transient large currents.
(5) If the overvoltage lasts too long, the gas discharge tube will
generate a lot of heat. In order to prevent damage to the protected
equipment due to overheating, the gas discharge tube should be
equipped with a failure protection card device. Nowadays, some new
products of gas discharge tubes have fail-safe cards.
