CG3 High-Voltage Gas Discharge Tubes

Littelfuse CG3 High-Voltage Gas Discharge Tubes (GDTs) are two-electrode, 1kV to 7.5kV devices designed for surge protection and high-isolation applications. Littelfuse CG3 GDTs are also designed for applications for which bias voltages or signal levels of several hundred volts are normally present. CG3 offers a low capacitance of <1.5pF and 5kA peak pulse current while operating over a -40°C to +90°C operating temperature range.
