SL1011B250A

Gas Discharge Tube (GDT) Products SL1011A/B and SL1411A Series SL1011A/B and SL1411A Series ® Description The SL1011A/B and SL1411A series provides high levels of protection against fast rising transients in the 100V/μs to 1kV/μs range usually caused by lightning disturbances. The SL1011A/B and SL1411A series offers low capacitance (< 1.5pf) which provides low insertion loss at high frequencies. SL1011A offers 5kA protection without destruction whereas the SL1011B and SL1411A offer 10kA surge protection without destruction (maximum single surge of 12kA @ 8/20μs). Agency Approvals AGENCY ® Features AGENCY FILE NUMBER • RoHS compliant • Low insertion loss • Excellent response to fast rising transients • Ultra low capacitance E128662 2 Electrode GDT Graphical Symbol • 5kA (SL1011A) or 10kA (SL1011B & SL1411A) surge capability tested with 8/20μs pulse as defined by IEC 61000-4-5 Applications • Broadband equipment • ADSL equipment • XDSL equipment ©2010 Littelfuse, Inc.
