Gas discharge tube, RF4055-000, LITTELFUSE

The gas discharge tube is placed in front of, and in parallel with, sensitive telecom equipment such as power lines, communication lines, signal lines and data transmission lines to help protect them from damage caused by transient surge voltages that may result from lightning strikes and equipment switching operations. This device does not influence the signal in normal operation. However, in the event of an overvoltage surge, such as a lightning strike, the GDT switches to a low impedance state and diverts the energy away from the sensitive equipment. The GDT offers a high level of surge protection and low capacitance, with the low capacitance also resulting in less signal distortion.
