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.

NOTE REGARDING 'SN' PRODUCTS: CG2 SN products were designed for surge

protection applications for which the radioactive isotope used in standard CG/CG2

devices is not desired. Since the end of 2007 all CG/CG2 products are non-radioactive.

See Part Numbering System diagram for additional ordering information.
