CG4 Series - Miniature Two Terminal SMT High Pressure Plasma Gas
Protector
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.
CG4 mini GDTs are high voltage (800- 3000V) components 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. CG4 mini GDTs can be
used in conjunction with Littelfuse MOVs (Metal Oxide Varistors) to
provide superior protection performance for AC applications.
