1. (All leads) Г?b applies between L1 and L2. Г?b1 applies between
L2 and 0.500 from the reference plane. Diameter is uncontrolled
in L1 and beyond 0.500 from the reference plane.
2. Measured from maximum diameter of the product.
3. О± is the basic spacing from the centerline of the tab to terminal 1
and ОІ is the basic spacing of each lead or lead position (N -1
places) from О±, looking at the bottom of the package.
4. N is the maximum number of terminal positions.
5. Dimensioning and tolerancing per ANSI Y14.5M -1982.
