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.
Agency Approvals
The CG Series (75V-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.
AGENCY
AGENCY FILE NUMBER
E1286621
E3201162
The CG2 Series (145V-1000V) is ideal for protecting
equipment where higher voltage limits and holdover
voltages are necessary.
NOTES:
1. Certified to UL 497B.
2. Only CG2300, CG2470, CG2600, CG2800 and CG221000. Certified to UL 1449.
