NOTES:

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

2. These dimensions should be measured at points .050 inch (1.27 mm) +.005 inch (+0.13 mm) �.000

inch (�0.00 mm) below seating plane.

3. The seating plane of the header shall be flat within .001 inch (0.03 mm) concave to .004 inch (0.10 mm)

convex .001 inch (0.03 mm) concave to .006 inch (0.15 mm) convex overall.

4. Pins 1 and 2 are internally connected with an internal jumper.

5. Devices with RB suffix (reverse polarity) have the cathode internally connected to the case.

6. In accordance with ASME Y14.5M, diameters are equivalent to Φx symbology.
