SL1002A350

Gas Discharge Tubes High Performance Beta Range RoHS Pb Greentube™ SL1002 Series Gas Plasma Arresters ® The Broadband Optimized™ SL1002 series has been especially developed for use in broadband equipment. Unique design features offer 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. These devices have Ultra low capacitance (typically 1.2pF or less) and present insignificant signal losses up to 1.5GHz. These devices are extremely robust and are able to divert a 5000A pulse without destruction. For AC Power Cross of long duration, overcurrent protection is recommended. FEATURES • RoHS compliant • Ultra Low Insertion Loss • Surface mountable • 5KA surge capability tested with 8/20µS pulse as defined by IEC 61000-4-5 • Excellent response to fast rising transients. • Can be used to meet Telcordia GR1089 without series resistance • 10/700 6KV capability, as per ITUT k.21, enhanced test level • 2000 Amp 2/10µS surge rating • Meets FCC part 68 10/160µs waveform, 200A test and 10/560µs waveform 100A test. 8 GAS DISCHARGE TUBES Applications: • Broadband equipment. • ADSL equipment. • XDSL equipment. • Satellite and CATV equipment. • General telecom equipment. 2 ELECTRODE GDT GRAPHICAL SYMBOL ORDERING INFORMATION SL 1002 A XXX All dimensions in mm Mechanical Specifications: SM=Surfacemount Voltage C= Core Type 2 Pole Arrester Weight: Materials: Device Marking: 0.63g (0.022 oz.)
