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.
2. The maximum limits of lead dimensions b and c or M shall be
measured at the centroid of the finished lead surfaces, when
solder dip or tin plate lead finish is applied.
3. Dimensions b1 and c1 apply to lead base metal only. Dimension
M applies to lead plating and finish thickness.
4. Corner leads (1, N, N/2, and N/2+1) may be configured with a
partial lead paddle. For this configuration dimension b3 replaces
dimension b2.
5. This dimension allows for off-center lid, meniscus, and glass
overrun.
6. Dimension Q shall be measured from the seating plane to the
base plane.
7. Measure dimension S1 at all four corners.
8. N is the maximum number of terminal positions.
9. Dimensioning and tolerancing per ANSI Y14.5M - 1982.
10. Controlling dimension: INCH.
