   3) Pins 1-3, 5-7 are 0.040" (1.02mm) diameter with 0.080" (2.03 mm) diameter standoff shoulders
   4) Pins 4 and 8 are 0.062" (1.57mm) diameter with 0.100" (2.54mm) diameter standoff shoulders.
   5) All Pins: Material - Copper Alloy, Finish (RoHS 6/6) - Matte Tin over Nickel plate
   6) Total Weight: 3.12 oz. (88.5 g)
   7) All dimensions in inches (mm)
        Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm)
                            x.xxx +/-0.010 in. (x.xx +/-0.25mm)
   8) Workmanship: Meets or exceeds IPC-A-610C Class II
   9) Recommended pin length is 0.03" (0.76mm) greater than the PCB thickness.
 10) A thermal interface material is required to assure proper heat transfer from the flanged baseplate to the cooling surface. Thermal grease may be used, or materials such as         Thermalloy's Grafoil or Bergquist HiFlow and Softflow. Other similar products are available from many heatsink manufacturers.
