This is an 1206 size SMD inductor. As described // in this file the 2 pads are along the horizontal X axis. // // This geometry includes it own SMD pads that are // 1.35 mm wide in X by 1.20 mm high in Y. The centers // of the pads are 3.35 mm apart along the X axis. // // This series choke is used in the power filters // for the higher current rails to the Ethernet Switch Chips, // for the SFP+ power, and for the 3V3 MiniPOD power // on the Hub card. // // The Wurth 742792116 has a DC resistance of about // 60 mOhm and has a current capacity of 2.5 Amps. // In a 1.30 mm high 1206 package it provides: // // about 9.5 Ohms of reactance at 1 MHz --> 1.6 uH // about 500 Ohms at 100 MHz // about 130 Ohms at 1 GHz // above 100 MHz there is a sharp drop in inductive reactance // the peak of inductive reactance is at about 40-50 MHz // inductive reactance down to 80% of its peak by 100 MHz // $abort_enable = @false; $$lock_windows(@on) ; $$snap_diagonal(@off) ; $$snap_orthogonal(@off) ; //---------------------------------------------------------------------------- $$create_pin("wurth_742792116_pad", @replace); $$page(0.0, 0.0, 0.0, @mm, 0.0, 0.0, [0.0,0.0,'PI$wurth_742792116_pad'] ); $$point_mode(@vertex); $$polygon( "PAD", , [ -0.675, -0.600, 0.675, -0.600, 0.675, 0.600, -0.675, 0.600 ] ); $$polygon( "SOLDER_MASK", , [ -0.725, -0.650, 0.725, -0.650, 0.725, 0.650, -0.725, 0.650 ] ); $$polygon( "PASTE_MASK", , [ -0.675, -0.600, 0.675, -0.600, 0.675, 0.600, -0.675, 0.600 ] ); $$attribute( "TERMINAL_SURFACE_DEFINITION", ""); //---------------------------------------------------------------------------- $$create_component("Wurth_1206_Ind", @replace); $$page(0.0, 0.0, 0.0, @mm, 0.0, 0.0, [0.0,0.0,'CO$Wurth_1206_Ind'] ); $$point_mode(@vertex); $$attribute( "COMPONENT_LAYOUT_TYPE", "surface"); $$attribute( "COMPONENT_LAYOUT_SURFACE", "both"); $$attribute( "COMPONENT_HEIGHT", "", , @scale , , [ 1.60, 0.0 ]); $$template_line_style( @Solid ); $$initial([ -2.60, 0.90 ], , @nosnap ); $$terminal([ 2.60, 0.90 ] ); $$terminal([ 2.60, -0.90 ] ); $$terminal([ -2.60, -0.90 ] ); $$terminal([ -2.60, 0.90 ] ); $$attribute( "COMPONENT_PLACEMENT_OUTLINE", "", @mark, @scale ); $$template_line_style( @Solid ); $$path( "SILKSCREEN", 0.20, , [ -2.30, 1.00, 2.30, 1.00 ]); $$path( "SILKSCREEN", 0.20, , [ -2.30, -1.00, 2.30, -1.00 ]); // Reference Designator is on SILKSCREEN_1 Layer. $$text( "SILKSCREEN", "^$ref", 0.0, 1.4, 1.5, @BC, 0, 0.7, 0.20, "std", "None", 0.0, 0.0 ); // Define the 2 pins on the wurth_742792116_inductor // pin #1 is to the left and pin #2 is on the right both on the X axis. $$attribute( "COMPONENT_PIN_DEFINITION", "1", , @scale , , [ -1.675, 0.00 ]); $$attribute( "COMPONENT_PADSTACK_OVERRIDE", "1, wurth_742792116_pad"); $$attribute( "COMPONENT_PIN_DEFINITION", "2", , @scale , , [ 1.675, 0.00 ]); $$attribute( "COMPONENT_PADSTACK_OVERRIDE", "2, wurth_742792116_pad");
