Gas Discharge Tube (GDT) Products
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.
