Notes:
1. Controlling dimension: millimeters. Inches shown for reference only.
2 ’D’ and ’E’ do not include mold flash or protrusions. Mold flash or protrusions shall not exceed 0,15 mm per side
3 Each lead centerline shall be located within ±0,10 mm of its exact true position.
4 Leads shall be coplanar within 0,08 mm at the seating plane.
5 Dimension ’B’ does not include dambar protrusion. The dambar protrusion(s) shall not cause the lead width
to exceed ’B’ maximum by more than 0,08 mm.
6 Dimension applies to the flat section of the lead between 0,10 mm and 0,25 mm from the lead tip.
7 ’A1’ is defined as the distance from the seating plane to the lowest point of the package body (base plane).
