1. To be determined at seating plane C.
2. Dimensions D1 and E1 do not include
mold protrusion. D1 and E1 are
maximum plastic body size
dimensions including mold mismatch.
3. Dimension b does not include dambar
protrusion. 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 0.10 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.
Notes:
1. Exact shape of each corner is optional.
2. Controlling dimension: mm.
