Ceramic gas discharge tube is in the discharge gap filled with inert gas medium is appropriate. With the high activity of electron emission material and discharge gas ignition mechanism, a special kind of metal ceramic structure formed by precious metal solder sealing of the discharge device. It can be used for transient overvoltage surge prevention, can also be used for ignition. The high impedance, low capacitance and high impact current is not available in other discharge tube. When the line has transient overvoltage, the discharge tube is broken down, and the impedance drops rapidly. Discharge tube will be a large current through the line to the ground or circuit drain, but also the voltage limit at low potential, thus protecting the line and equipment. When the voltage surge disappears, and quickly restored to more than 109 high resistance state, to ensure the normal operation of the circuit. Ceramic gas discharge tube has the following characteristics
1, lightning arrester from the 100V/s slow spike to 10kV/ s high speed burst can provide fast response speed.
2, to provide a stable breakdown voltage
3, high insulation resistance, high insulation resistance characteristics of the lightning arrester can be at high temperature and high humidity also has a good response.
4, low capacitance characteristics, low capacitance characteristics can reduce interference or reduce the transmission loss in high frequency operating environment.
5, higher than the hold voltage, can quickly respond to the high state to ensure the safety of continuous operation.
6, without crossing the voltage, in the multi pole lightning arrester without transverse voltage.
7, the use of a long period of time in general use for more than 10 years.
8, sealed and anti-corrosion of the lightning protection, strong and fully enclosed arrester to avoid leakage and vibration can also provide better protection. The appearance of the product is more flexible for application.
9, the circuit design is simple, and has no effect on the original circuit.

The use of ceramic gas discharge tube
Ceramic gas discharge tube is widely used, can be used for signal protection, AC outdoor distribution box power lightning protection, overvoltage protection, signal level protection, communication equipment, switching power supply, air conditioning power etc..
