| High Performance Beta Range RoHS Pb GreentubeTM SL0902 Series Gas Plasma Arresters (R) The Broadband OptimizedTM SL0902 series has been especially developed to offer high surge ratings in a miniature package. Unique design features offer high levels of performance on fast rising transients in the domain of 100V/s to 1kV/ss, which are those most likely from induced lightning disturbances. The device offers low insertion loss, so is well suited to braodband equipment. The capacitance does not vary with voltage, so will not cause operational problems with ADSL2+ where capacitance variation across Tip and Ring is undesirable. These devices are extremely robust and are able to divert a 2500A pulse without destruction. For AC Power Cross of long duration, overcurrent protection is recommended. FEATURES * RoHS compliant * GHz working frequency * Excellent stability on multiple pulse duty cycle * Excellent response to fast rising transients. * Ultra Low Insertion Loss * Surface mountable * 2.5KA surge capability tested with 8/20mS pulse 5.0 0.2 as defined by IEC 61000-4-5 5.0 0.2 Applications: * Broadband equipment. * ADSL equipment, including ADSL2+. * XDSL equipment. * Satellite and CATV equipment. * General telecom equipment.
