Notes:
1. To be determined at seating plane.
2. Dimensions D1 and E 1do not include mold protrusion.
D1 and E1 are maximum plastic body size dimensions
including mold mismatch.
3. Dimensions b do not include dambar protrusion. Total in
excess of the b dimension at maximum material condition.
Dambar cannot be located on the lower radius of the foot.
4. Exact shape of each corner is optional.
5. These dimensions apply to the flat section of the lead
between 0.10mm and 0.25mm from the lead tip.
6. A1 is defined as the distance from the seating plane to the
lowest point of the package body.
7. Controlling dimension: millimeter.
8. Reference documents: JEDEC MS-026 , BBC.
