NOTES:
1. Dimensions are in inches.
2. Millimeters are given for general information only.
3. These dimensions shall be measured at points .050 inch (1.27 mm) and .055 inch (1.40 mm)
below the seating plane. When gauge is not used, measurement will be made at the seating
plane.
4. 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.
5. These dimensions pertain to the 2N6764 and 2N6766 types.
6. These dimensions pertain to the 2N6768 and 2N6770 types.
7. Mounting holes shall be deburred on the seating plane side.
8. Drain is electrically connected to the case.
