the gl series was developed specifically to deliver repeatable and reliable ultra broad band performance up through 40 + ghz. the gl series of inductors provide ultra-low insertion loss, excellent return loss and extreme part to part performance repeatability. the pyramid shape of the gl series provides for maximum inductance in the space available. the gl series was developed using a powdered iron core and gold plated terminations that allow for easy use in hand solder applications. the combination of flat frequency response with the ultra-low insertion loss makes this an ideal component for optical data systems, transimpedance amplifers and test equipment. gl series ultra broad band inductor advantages ? ultra broad band performance ? ultra-low insertion loss ? excellent return loss through 40 ghz ? flat frequency response ? part to part performance repeatability ? rugged powdered iron core applications ? communication customers ? receiver optical sub-assemblies ? transimpedance amplifier customers ? test equipment manufacturers mechanical specifications inches (mm) inductance (h) l h # of turns 2 0.102 0.002 (2.59 0.051) 0.065 0.002 (1.65 0.051) 46 turns #44 awg cu 6 0.182 0.003 (4.62 0.076) 0.073 0.002 (1.85 0.051) 80 turns #44 awg cu 11 0.182 0.003 (4.62 0.076) 0.072 0.002 (1.83 0.051) 110 turns #47 awg cu electrical specifications operating insertion return rdc () @ 20oc, idc (ma), number of cu wire size inductance (h) frequency loss loss 10 ma current dc max. turns (awg) range 2 2.3 mhz to 40 ghz 0.5 db typ. -17 db typ. 1.45 250 46 44 6 880 khz to 40 ghz 0.6 db typ. -18 db typ. 2.90 200 80 44 11 500 khz to 40 ghz 0.4 db typ. -18 db typ. 7.00 115 110 47 operating temperature: -55oc to + 125oc h uninsulated 0.20 +0.10 -.05 (5.08 + 2.54 -1.27) uninsulated .40 +.150 -.05 (10.16 +3.81 -1.27) insulated .030 .020 (.762 .508) insulated .001 (.025) max. .011 (.280) max. l
