Description

Littelfuse CG4 Gas Discharge Tubes (GDT) series

provides high levels of protection against fast rising

transients caused by lightning disturbances. Offered

in a miniature surface mount package, it has a surge

rating of 3kA 8/20μs.

Littelfuse CG4 mini GDTs are high voltage (800-

3000V) devices designed for surge protection and

high isolation applications. It is also suitable for

applications for which bias voltage or signal levels of

several hundred volts are normally present.

This CG4 mini GDTs are also suitable for applications

with bias voltages or signal levels of several hundred

volts. It can be used in conjunction with Littelfuse

MOV (Metal Oxide Varistor) to provide superior

protection performance.
