A) Part Marking: Line 1: (1st digit indicates the inductance value per part marking

designator in chart above)

(2nd digit is a bi-weekly production date code)

(3rd digit is the last digit of the year produced)

Line 2: XX (indicates the product size code)

Do not route traces or vias underneath the inductor
