1 SL12A Series SL12A Series RoHS Agency Approvals AGENCY AGENCY FILE NUMBER E Electrode GDT Graphical Symbol Additional Information Description The Broadband Optimized SL12A series has been especially developed for use in broadband equipment. Special design features provide high levels of protection against fast rising transients in the 1V/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 5A pulse without destruction. For AC Power Cross of long duration, overcurrent protection is recommended. Features RoHS compliant/leadfree Ultra low insertion loss Surface mountable 5kA surge capability tested with 8/2μS Pulse as defined by IEC Excellent response to fast rising transients Can be used to meet Telcordia GR189 without series resistance 1/7 6kV capability, as per ITU-T Rec. K.21, enhanced test level 2 A 2/1μs surge rating Meet FCC part 68 1/16μs waveform, 2A test and 1/56μs waveform 1A test Halogen-free Datasheet Resources Samples Applications Broadband equipment ADSL equipment XDSL equipment Satellite and CATV equipment General telecom equipment 215 Littelfuse, Inc.
