CG110L Littelfuse

Gas Discharge Tubes CG/CG2 Series RoHS CG/CG2 Series Description Littelfuses 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 Agency Approvals leads, to serve a variety of mounting methods. The CG Series (75V-110V) is ideal for protection AGENCY AGENCY FILE NUMBER of test and communication equipment and other 1 E128662 devices in which low voltage limits and extremely low arc voltages are required. 2 E320116 NOTES: The CG2 Series (145V-1000V) is ideal for protecting 1. Certified to UL 497B. equipment where higher voltage limits and holdover 2. Only CG2300, CG2470, CG2600, CG2800 and CG221000. Certified to UL 1449. voltages are necessary. 2 Electrode GDT Graphical Symbol Features RoHS and Lead-free Meets REA PE-80 compliant Available in surface Rugged Ceramic-Metal mount, and a variety of construction lead options options Additional Information Low Capacitance RoHS Compliant and (<1.5pf) Lead-Free Applications Datasheet Resources SamplesSamples Communication lines Instrumentation circuits CG/CG2 and equipment Medical electronics CATV equipment ADSL equipment Test equipment Telecom SLIC Data lines protection Power supplies 2017 Littelfuse, Inc.
