NOTES:

1. Dimensions are in inches. Millimeters are given for general information only.

2 Body contour is optional within zone defined by dimension CD.

3. At both ends.

4. Both terminals.

5. Dimension LD applies between L1 and LL. Lead diameter shall not exceed twice dimension LD within

dimension L1. Diameter is uncontrolled in dimension L1.

6. Two holes.

7. These dimensions shall be measured at points .050 inch (1.27 mm) to .055 inch (1.40 mm) below the

seating plane. When gauge is not used, measurement shall be made at 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.

9. The collector shall be electrically connected to the case.

10. In accordance with ASME Y14.5M, diameters are equivalent to φ symbology.
