2. All dimensioning and tolerancing conforms to ASME Y14.5M-1994.
3. To be determined at seating plane.
4. Dimensions D1 and E1 do not include mold protrusions. Allowable
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.
5. 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 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.
