Gas Discharge Tube (GDT) Products SL1002A Series SL1002A Series ® Description The Broadband Optimized™ SL1002A series has been especially developed for use in broadband equipment. Special design features provide high levels of protection against fast rising transients in the 100V/μs to 1kV/μs range usually caused by lightning disturbances. These devices have ultra low capacitance (typically 1.2pF or less) and present insignificant signal losses up to 1.5GHz. These devices are extremely robust and are able to divert a 5000A pulse without destruction. For AC Power Cross of long duration, overcurrent protection is recommended. Agency Approvals Features AGENCY ® AGENCY FILE NUMBER • RoHS compliant/Leadfree • Ultra low insertion loss • Surface mountable • 5kA surge capability tested with 8/20μS– Pulse as defined by IEC 61000-4-5 • Excellent response to fast rising transients • Can be used to meet Telcordia GR1089 without series resistance E128662 2 Electrode GDT Graphical Symbol • 10/700 6kV capability, as per ITU-T Rec.
