Notes:

1.All dimensions are in millimeters unless otherwise noted.

2.Dimensions b & c apply to the flat section of the lead foot between 0.10 and 0.25mm from the lead tip. The base metal is exposed at the lead tip.

3.Dimensions D1 and E1 do not include mold protrusions. Maximum allowed protrusion is 0.25mm per side. D1 and E1 are maximum plastic body size dimensions including mold mismatch.

4.The pin 1 identifier may vary, but is always located within the zone indicated.
