Product Description

Products Description

• Gas Discharge Tube (GDT) is an electronic device that operates based on the principle of gas discharge. It has a wide range of applications in various electronic circuits and devices, mainly used for overvoltage protection and transient voltage suppression.

 

Features:

• Large flow rate: Gas discharge tubes can withstand large transient currents
• High impulse breakdown voltage: The breakdown voltage of gas discharge tubes is high, which means they can start working at higher voltages to protect other components in the circuit.
• Small capacitance: The capacitance of gas discharge tubes is usually very small, which makes their application in high-frequency and high-speed data lines possible.
• Small size and low cost: Gas discharge tubes are typically designed to be compact, take up less space, and have relatively low manufacturing costs, making them economically advantageous in various applications.
• Stable performance and long lifespan: The performance of gas discharge tubes is usually very stable and has a long lifespan, which allows them to maintain good performance in long-term use.
