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.
