Notes:

All dimensions and tolerances conform to ANSI Y14.5M-1982.

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.

Pin 1 identifier is optional.

Dimension ND: Number of terminals.

Dimension ND: Number of terminals per package edge.

"L" is the length of terminal for soldering to a substrate.

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 for 0.4mm and 0.5mm

pitch packages.
