PRODUCT SPECIFICATION
Notes:
1. All dimensions and tolerances conform to ANSI Y14.5M-1982.
2. 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.
3. Pin 1 identifier is optional.
4. Dimension N: Number of terminals.
5. Dimension ND: Number of terminals per package edge.
6. "L" is the length of terminal for soldering to a substrate.
7. 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 can not be
located on the lower radius or the foot. Minimum space between
protrusion and an adjacent lead is 0.07mm.
