CG/CG2 Series

CG/CG2 Series

Description

Littelfuse highly reliable CG/CG2 Series GDTs provide

a high degree of surge protection in a small size ideal

for board level circuit protection.

GDTs function as switches which dissipate a

minimum amount of energy and therefore handle

currents that far surpass other types of transient

voltage protection. Their gas-filled, rugged ceramic

metal construction make them well suited to adverse

environments.

The CG/CG2 series comes in a variety of forms

including surface mount, core, straight and shaped

leads, to serve a variety of mounting methods.

The CG Series (75-110V) is ideal for protection of test

and communication equipment and other devices

in which low voltage limits and extremely low arc

voltages are required.

The CG2 Series (145V-1000V) is ideal for protecting

equipment where higher voltage limits and holdover

voltages are necessary.
