Not drawn to scale. 0.50 ± 0.20 -E- Seating Plane -C- Base Plane 0.23 ± 0.05 (lead width) (NOTE 5) NOTES: 1. Datum plane -E- is located at the mold parting line and is coincident with the bottom of the leads where the leads exit the plastic body. 2. Datums -A-, -B-, and -D- to be determined at datum plane -E-. 3. To be determined at seating plane -C-. 4. These dimensions do not include mold protrusion. Allowable protrusion is 0.25 mm per side. These dimensions do not include mold mismatch and are determined at datum plane -E-. 5. This dimension does not include Dambar protrusion. Allowable Dambar protrusion shall be 0.08 mm total in excess of this dimension at maximum material condition. Dambar cannot be located on the lower radius or the foot. Minimum spacing between adjacent leads to be 0.07 mm. 6. Coplanarity = 0.08 mm and is the difference between the highest lead and the seating plane, -C-. 7. Controlling dimension = millimeter. 8.
