| Gas Discharge Tubes Omega Range RoHS Pb GreentubeTM SL1024B Series Gas Plasma Arresters (R) The SL1024B series offers high levels of current handling on fast rising transients created by induced Lightning disturbances. These devices are extremely robust and are able to divert pulses of 20,000 Amps. The SL1024B also features ultra low capacitance (typically 1pF or less) making them ideal for the protection of high-speed transmission equipment. FEATURES * RoHS compliant except `RS' suffix * Low insertion loss * Excellent response to fast rising transients. * Ultra low capacitance. * 20KA surge capability tested with 8/20s pulse as defined by IEC 61000-4-5 * Available with thermal failsafe option (add `F' or `S' suffix to part number) Applications: * Broadband equipment. * ADSL equipment. * XDSL equipment. * Satellite and CATV equipment. * Splitters * General telecom equipment.
