NOTES:

1.

Index area: A notch or a pin one identification mark shall be located

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.

The b2 minimum dimension of .045 inch (1.14 mm) was implemented 30

September 1992. Until that date, a minimum dimension of .038 (0.97 mm)

was acceptable. See 5.2.4

5.

Corner leads (1, N, N/2, and N/2+1) may be configured as shown in detail

A. For this configuration dimension b3 replaces dimension b2.

6.

This dimension allows for off-center lid, meniscus, and glass overrun.

8.

Pointed or rounded lead tips as shown in details B and C are preferred to

ease insertion, but are not mandatory.

9.

Dimension Q shall be measured from the seating plane to the base plane.

10.

Measure dimension S1 at all four corners, see 5.2.5.

11.

Measure dimension S2 from the top of the ceramic body to the nearest

metallization or lead

12.

N is the maximum number of terminal positions.

14.

See tables VI and VII for descriptive type designators.
