Notes:
1. Dimensions D1 and E1 do not include
mold protrusion, but mold mismatch is
included. Allowable protrusion is
0.25mm/0.010 per side.
2. Dimension B does not include Dambar
protrusion. Allowable protrusion is
0.08mm/0.003 total in excess of the B
dimension at maximum material
condition. Dambar cannot be located on
the lower radius or the foot.
3. Controlling dimension: millimeter.
