NOTES:
1. Index area: A notch or a pin one identification mark shall be locat-
ed adjacent to pin one and shall be located within the shaded
area shown. The manufacturer’s identification shall not be used
as a pin one identification mark. Alternately, a tab (dimension k)
may be used to identify pin one.
2. If a pin one identification mark is used in addition to a tab, the lim-
its of dimension k do not apply.
3. This dimension allows for off-center lid, meniscus, and glass
overrun.
4. Dimensions b1 and c1 apply to lead base metal only. Dimension
M applies to lead plating and finish thickness. The maximum lim-
its of lead dimensions b and c or M shall be measured at the cen-
troid of the finished lead surfaces, when solder dip or tin plate
lead finish is applied.
5. N is the maximum number of terminal positions.
6. Measure dimension S1 at all four corners.
7. For bottom-brazed lead packages, no organic or polymeric mate-
rials shall be molded to the bottom of the package to cover the
leads.
8. Dimension Q shall be measured at the point of exit (beyond the
meniscus) of the lead from the body. Dimension Q minimum
shall be reduced by 0.0015 inch (0.038mm) maximum when sol-
der dip lead finish is applied.
9. Dimensioning and tolerancing per ANSI Y14.5M - 1982.
10. Controlling dimension: INCH
