Product overview
GDT, the full name is Gas Discharge Tubes, is a tubular ceramic cavity, through the combination of metal electrodes, a discharge gap element made by the high temperature welding process of discharge gap element with stable discharge characteristics. The resistance value of this type of device varies from G ohm to Ohm depending on the voltage value loaded on both ends of the device. The resistance value can complete the transition in 100 nanoseconds. Based on this characteristic, most of the GDT are connected in parallel in the system circuit to prevent overvoltage from damaging other components at the back end. Due to the continuous flow characteristic of gas discharge, it is rarely used in non-power lines alone, which can effectively suppress electromagnetic interference such as Surge. It can be widely used in telephone, DSL, program-controlled switchboard, network switch, switching power supply to ground protection, industrial communication, cable TV, automotive HID ignition system, Surge protective device and other products.

The ACPA GDT sold by our company has various appearances such as square and round. According to the number of electrodes, it can be divided into two categories: 2R and 3R. According to the package, it can be divided into two types: patch and plug-in, including 2R, 3R, 2RM, 3RM, 2SM, 3SM, 4532, 3216, AE and other series.
