//
//
//
//  This is the geometry for the  Wurth 744272102
//  common mode choke  and  is being used on the
//  100 Volt input power bus on the Disco-Kraken.
//
//  This common mode choke is:  1 mH on each side,
//  0.18 Ohms on each side,  rated for 950 mA
//  and has a leakage inductance of about  5.9 uH.
//
//  The insulation test voltage is  1000 VAC.
//
//  Its overall external size is about:
//  10 mm  in X  by  8.7 mm  in Y.
//
//  This SMD inductor is about  6.5 mm  tall.
//
//  The 4 pads are square  2.7 mm  on a side.
//
//  This geometry includes it own SMD pads.The centers
//  of the pads are  7.62 mm  apart along the X axis
//  and  6.22 mm  apart along the Y axis.
//
//
//  The center of this geometry is in the center
//
//  Pin #1 is in the NE corner and the pins are numbered
//  around the device in the normal CCW layout.
//
//  Pins #1 and #2 are one winding.  Pins #3 and #4
//  are the other winding.
