the case.
3. Body contour is optional within zone defined by dimension CD.
4. Applies to both ends.
5. Applies to both terminals.
6. Dimension LD applies between L1 and LL. Lead diameter shall not exceed twice dimension LD within
dimension L1. Diameter is uncontrolled in dimension L1.
7. These dimensions shall be measured at points .050 inch (1.27 mm) to .055 inch (1.4 mm) below the
seating plane. When gauge is not used, measurement will be made at the seating plane.
8. The seating plane of the header shall be flat within .001 inch (0.03 mm) concave to .004 inch (0.10
mm) convex inside a .930 inch (23.62 mm) diameter circle on the center of the header and flat
within .001 inch (0.03 mm) concave to .006 inch (0.15 mm) convex overall.
