Dimensions D1 and E1 do not include mold protrusion. Allowable protrusion is 0.25mm per side. D1 and E1 are maximum plastic body size dimensions including mold mismatch. 2. 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 0.08mm. Dambar cannot be located on the lower radius or the foot. Minimum space between protrusion and an adjacent lead is 0.07mm for 0.4mm and 0.5mm pitch packages. 3. All dimensions of 44L were based on those of 48L since they are not mentioned in JEDEC spec MS-026. θ2 R1 R2 -HS L GAUGE PLANE 0.25mm θ3 DETAIL "A" 1
