Gas Discharge Tubes High Performance Beta Range RoHS Greentube™ SL1011A Series Gas Plasma Arresters Pb ® 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 8 pulse as defined by IEC 61000-4-5 GAS DISCHARGE TUBES Applications: • Broadband equipment. • ADSL equipment. 6.0 + _ 0.2 • XDSL equipment. 6.0 _ + 0.2 • Satellite and CATV equipment. 8.0 _ + 0.2 60 + _ 0.4 • General telecom equipment.
