REGISTERED JACK (RJ) CONNECTORS
|
Gas arrestors, also known as gas discharge tubes (GDTs), are surge protection devices designed to protect sensitive electronic equipment from voltage transients.
They operate by using an inert gas sealed within a glass or ceramic enclosure that ionizes and conducts electricity when a high voltage surge occurs. This effectively diverts the excess energy away from protected circuits.
Gas arrestors are commonly used in telecom systems, power lines, and data interfaces due to their high surge-handling capacity, fast response time, and ability to return to a non-conductive state after the surge passes.
