SL1011A

Gas Discharge Tubes High Performance Beta Range RoHS Pb Greentube™ SL1011A Series Gas Plasma Arresters ® The SL1011A series offers high levels of performance on fast rising transients in the domain of 100V/µS to 1KV/µS, which are those most likely from induced Lightning disturbances. The SL1011A series also features ultra low capacitance (typically 1pF or less) making them ideal for the protection of high-speed transmission equipment. These devices are extremely robust and are able to divert a 5,000A pulse without destruction. FEATURES • RoHS compliant • Low insertion loss • Excellent response to fast rising transients. • Ultra low capacitance. • 5KA surge capability tested with 8/20µs pulse as defined by IEC 61000-4-5 • 20,000 A single shot surge capability tested with 8/20µs pulse as defined by IEC 61000-4-5 8 GAS DISCHARGE TUBES 329 Applications: • Broadband equipment. • ADSL equipment. • XDSL equipment. • Satellite and CATV equipment. • General telecom equipment. 60 + 0.4 _ 6.0 + 0.2 _ 6.0 _ 0.2 + 8.0 _ 0.2 + SL1011AxxxA SL1011AxxxC All dimensions in mm 2 ELECTRODE GDT GRAPHICAL SYMBOL ORDERING INFORMATION SL 1011 A Voltage Pin Configuration A = Leaded C = Core Mechanical Specifications: Weight: Materials: 2.7g (0.095 oz.)
