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.

Features:
  • Rugged Ceramic-Metal construction
  • Low Capacitance(<1.5pf)
  • Meets REA PE-80
  • Available in surface mount, and a variety of lead options options

Applications:

  • Communication lines and equipment
  • CATV equipment
  • Test equipment
  • Data lines
  • Power supplies
  • Instrumentation circuits
  • Medical electronics
  • ADSL equipment
  • Telecom SLIC protection
