SMD1812 Series Surge Arresters SMD

Gas discharge tubes eliminate the surge voltage by the principle of gas ionization discharge. They have high insulation resistance, low capacitance and low leakage current to ensure minimal effect on normal operation of equipment.

Circuit Protection2Pole GDTs (ceramic gas discharge tubes), are commonly used to help protect sensitive telecom equipment such as communication lines, signal lines and data transmission lines from damage caused by transient surge voltages that typically result from lightning strikes and equipment switching operations.

Circuit Protection GDTs offer a high level of surge protection, low capacitance and a broad array of breakover voltage levels, making them suitable for applications such as MDF (Main Distribution Frame) modules, high data-rate telecom applications (e.g. ADSL, VDSL), and surge protection on power lines. Circuit Protection GDTs can help equipment meet the most stringent regulatory standards.
