protrusion is 0.25 mm per side. D1 and E1 are maximum plastic body size
dimensions including mold mismatch. Dimensions D1 and E1 shall be
determined at Datum plane.
protrusion shall not cause the lead width to exceed the maximum b
dimension by more than 0.08 mm. Dambar can not be located on the lower
radius or the foot. The minimum space between protrusion and an adjacent
lead shall not be less than 0.07 mm.
