Allowable protrusion is 0.25 mm per side. D1 and E1 are maximum plastic body size dimensions including mold mismatch. 5. Details of Pin 1 identifier optional, but must be located within the zone indicated. 6. All dimensions are in millimeters. 7. Dimension b does not include Dambar protrusion. Allowable Dambar protrusion shall not cause the lead width to exceed the maximum b dimension by more than 0.08 mm. Dambar cannot be located on the lower radius or the foot. Minimum space between protrusion and an adjacent lead is 0.07 mm for 0.4 mm and 0.5 mm pitch packages. 8. Exact shape of each corner is optional. 9. These dimensions apply to the flat section of the lead between 0.10 mm and 0.25 mm from the lead tip. 10. A1 is defined as the distance from the seating plane to the lowest point of the package body.
