NOTES:
1. Controlling dimension: INCH. Converted millimeter dimensions
are not necessarily exact.
2. Dimensions and tolerancing per ANSI Y14.5M-1982.
3. Dimensions D1 and E1 do not include mold protrusions. Allow-
able mold protrusion is 0.010 inch (0.25mm) per side. Dimen-
sions D1 and E1 include mold mismatch and are measured at
the extreme material condition at the body parting line.
4. To be measured at seating plane
5. Centerline to be determined where center leads exit plastic body.
6. “N” is the number of terminal positions.
