Introduction to Gas Discharge Tube Arresters (GDT)Gas Discharge Tube Arresters (GDT) are commonly used components designed to protect electronic circuits and radio equipment from very high voltage spikes. A GDT works similar to an electronic fuse, where a surge of excess energy is dissipated and the device is designed to blow without causing damage to the protected circuit. GDTs are typically designed to protect against lightning-induced surge currents, ESD (electrostatic discharge) and static electricity, and they do an effective job of absorbing and dispersing the excess energy.The GDT consists of a sealed-end tube filled with a low-pressure, electrically charged gas, such as argon and nitrogen. As electrical current passes through the tube, electrons collide with the gas molecules, which causes the molecules to break down into smaller, electrically charged atoms. These charged atoms then cause a spark to form inside the tube. The spark, in turn, dissipates the excess energy, thus protecting the attached circuit from damage.GTCN38-421M-Q10-FS Application Field and Working PrincipleThe GTCN38-421M-Q10-FS is gas discharge tube arrester with a maximum voltage rating of 700V, a rated voltage of 5-500V and an operating frequency of 50-60Hz. It is used to protect electrical equipment and circuits from high transient voltages caused by lightning, ESD, or electrical surges.The GTCN38-421M-Q10-FS is also designed to suppress over-voltage surge levels that may occur due to short circuit or other outage activities. It can handle over-voltage surge levels up to 14kV. The GTCN38-421M-Q10-FS is thermally protected and can operate safely in temperatures between -30°C and +65°C.GTCN38-421M-Q10-FS Gas Discharge Tube Arresters, like all GDTs, work on the principle of sparkgap breakdown. An internal sparkgap assembly creates a pocket of charged gas molecules which act as a trap for electrical surges. When an over-voltage surge passes through the GDT, the electrical current collides with the trapped molecules, causing them to break down and spark. As the spark dissipates the excess energy, the surge is harmlessly discharged. This process ensures that the equipment and circuits connected to the GDT are protected from the potentially damaging effects of the surge current.The GTCN38-421M-Q10-FS has a very fast response time. It takes less than one millionth of a second for the GDT to respond and reliably suppress transient surges. Its long working life can easily reach up to several thousands of hours and can continue to protect your circuits for many years.The GTCN38-421M-Q10-FS is used in a variety of applications, including power distribution systems, telecommunications networks, marine navigation equipment, high-voltage medical equipment, and radar systems. GTCN38-421M-Q10-FS Gas Discharge Tube Arresters are designed to withstand high inrush currents, wide temperature ranges, and a wide range of voltages. They are also designed to be as small and lightweight as possible to minimize power loss and make them easier to install in tight spaces. In conclusion, the GTCN38-421M-Q10-FS Gas Discharge Tube Arrester is an effective, highly reliable device that is capable of protecting electronic circuits and associated equipment from harmful high-voltage surges. With its fast response time, long working life, and ability to withstand high inrush currents, this GDT is a great choice for any application.
