Gas Discharge Tube (GDT) Products SL1003A Series SL1003A Series ® Description The SL1003A series has been especially developed for 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 1.5pF 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, over-current protection is recommended. Agency Approvals AGENCY ® Features • RoHS compliant • Low insertion loss • Surface mountable • 5kA surge capability tested with 8/20/μs pulse as defined by IEC 61000-4-5 • GHz working frequency • Excellent response to fast rising transients AGENCY FILE NUMBER E128662 3 Electrode GDT Graphical Symbol • Can be used to meet Telcordia GR1089 without series resistance • 10/700 6kV capability, as per ITU-Tk.21, enhanced test level • 2000 Amp 2/10μs surge rating Applications • Broadband equipment • ADSL equipment • XDSL equipment SL1003A Series 40 Revised: November 10, 2009 • Satellite and CATV equipment • General telecom equipment ©2009 Littelfuse, Inc.
