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 CG10 series comes different forms including surface mount, straight leads, to serve a variety of mounting methods. ## **Features** - High surge current rating ■ Available in surface mount - ■ Rugged ceramic-metal and axial straight leads construction options - Low Capacitance ■ RoHS-compliant and lead-free (<1.0 pf) **Agency Approvals** Low Capacitance ■ RoHS-compliant and lead-free (<1.0 pf) **Agency Agency File Number** ■ High operating temperature W E128662 up to 125 ºC ## **Applications** ## **Two Electrode GDT Graphical Symbol** - Communication lines and ■ Instrumentation circuits equipment ■ Medical electronics - ■ CATV equipment ■ ADSL equipment - Test equipment ■ Telecom SLIC protection - Data lines ■ Alarm system - Power supplies ## **Electrical Characteristics** |**Part**
