Gas Discharge Tubes High Performance Beta Range RoHS Pb Greentube™ SL1003 Series Gas Plasma Arresters ® The SL1003 series has been especially developed for 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 • Low insertion loss • Surface mountable • 5KA surge capability tested with 8/20µS pulse as defined by IEC 61000-4-5 • GHz working frequency. • 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 Applications: • Broadband equipment. • ADSL equipment. • XDSL equipment. • Satellite and CATV equipment. • General telecom equipment. 3 ELECTRODE GDT GRAPHICAL SYMBOL ORDERING INFORMATION SL 1003 A XXX All dimensions in mm Pin Configuration Voltage Type 3 Pole Arrester C= Core R= Leaded w w w. l i t t e l f u s e . c o m 331 Gas Discharge Tubes High Performance Beta Range RoHS Pb Greentube™ SL1003 Series Gas Plasma Arresters ® LITTELFUSE 3 TERMINAL MINI ARRESTER SERIES TOTALLY NON-RADIOACTIVE, UL RECOGNIZED Part Number Max Dynamic Max Dynamic Max Repetitive Breakover Impulse Breakover DC Voltage Voltage @ Discharge Voltage @ @100V/sec 100 V/µs (Vbr) 1 kV/µs (Vbr) Current2 (kA) (V) SL1003A090 90 600 700 5 SL1003A230 350 500 SL1003A250 SL1003A260 230 250 260 400 SL1003A300 300 SL1003A350 SL1003A400 SL1003A450 350 600 600 650 700 800 800 5 5 5 5 5 5 5 420 450 500 550 650 400 450 Nominal Max Holdover On-State Alternating 4 1 Capacitance Voltage Voltage @ Discharge (pF) (V) Current3 (A) 1A (V) 1.2 9 50 5 20 1x10 @50V 1.2 135 5 20 1x109 @100V 1.2 135 5 20 1x109 @100V Insulation Resistance7 (Ω) 1x109 @100V 1x109 @100V 1x109 @100V 1x109 @100V 1x109 @100V 5 5 5 5 5 1.2 1.2 1.2 1.2 1.2 135 135 135 135 135 20 20 20 20 20 Notes: (1) Tested according to ITU-T Rec.K12 (2) 10 shots, 8/20µs wave form per IEC 61000-4-5 (3) Measured @ 100 Volts (4) Measured @ 1 MHz, 0 volt bias 8 GAS DISCHARGE TUBES (5) Measured with 2/10µs wave form (6) Measured with 10/350µs wave form (7) Measured @ 100VDC except 90V which is measured at 50VDC Voltage vs Time Characteristic Typical Inser tion loss figures Max dynamic breakover voltage @1.0 GHz = 0.01dB @1.4 GHz = 0.1dB Voltage (V) @1.8 GHz = 0.53dB @2.1 GHz = 0.81dB @2.45 GHz = 1.0dB @2.8 GHz = 1.2dB Hold-over voltage @3.1 GHz= 1.5dB On-State voltage 0 200 400 600 800 1000 @3.5 GHz = 2.1dB 1200 Time (ns) 332 w w w. l i t t e l f u s e . c o m Gas Discharge Tubes High Performance Beta Range RoHS Pb Greentube™ SL1003 Series Gas Plasma Arresters Profile for reflow soldering ® Profile for wave soldering 250 300 225 T 1 max = 266oC Solder Flow Area 175 150 T 1 = 239oC 125 100 200 75 Temperature (˚C) Temperature ˚C 200 50 25 0 0 50 100 150 200 250 300 Time in seconds 350 400 450 Tm = 179oC Forced Cooling Preheating Area 500 100 10 20 30 40 Time(seconds) Notes: T1 max T1 Tm o = Maximum TabTemperature = 266 C = Flow Tempearture of Solder = 239oC o = Melting Point of Solder = 179 C Tamb = 25 C o o Maximum permissible rate of temperature change = 7C / sec w w w. l i t t e l f u s e . c o m 333
