Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube Arresters (GDTs) are devices that protect electronic and electrical systems from the effects of overvoltage and lightning surges. They are typically used in both residential and commercial buildings, as well as on outdoor power and communication systems. They are also used in electrical power distribution systems, industrial control systems, and telecommunications networks.In essence, GDTs work by creating an “arrestor” in the form of a tube filled with a gas, typically Argon or Nitrogen. When an overvoltage is applied, the gas inside reacts with an electric arc, dissipating the surge of electricity and protecting the equipment.The SL1021B250CF is a Gas Discharge Tube Arrestor that is designed for protection of high speed data communication lines and amplifier circuitry against surges and transients. It offers superior protection for CAT6 and CAT5 cables, as well as high frequency amplifier circuits in communication systems. In addition, the SL1021B250CF is UL listed and can be used in many applications requiring temperature sensitive operation.The operating principle of the SL1021B250CF is based on the creation of an electric arc inside its gas-filled tube. When a surge is applied, the voltage increases as the electric current travels through the tube to the surface of the cathode, which then ignites the gas in the tube. The arc formed by the gas dissipates the energy from the surge, thereby protecting the connected equipment and preventing damage.The SL1021B250CJ is suitable for use in applications that require broadband protection from transient voltages of up to 250VDC, Impedance ratings of 2.5 ohms minimum at 100KHz for low frequency and 10.0 ohms minimum at 2.0GHz for high frequency applications. The 1021 Series features a wide operating temperature range of -40°C to +72°C and is RoHS compliant.The SL1021B250CJ is ideal for high frequency applications such as CAT6 and CAT5 cables, high frequency amplifier circuits, and other equipment requiring protection from transient voltage. It provides reliable protection at a competitive price, making it an appropriate choice for many applications.Overall, the SL1021B250CJ GDT is a good solution for the protection of data transmission and amplifier circuits against overvoltage or lightning surges. It features a high level of performance and efficiency, making it a cost-effective solution for many applications.
