NOTES:

1.

Dimension are in inches.

2.

Metric equivalents are given for general information only.

3.

Beyond r (radius) maximum, TW shall be held for a minimum length of .011 (0.28 mm).

4.

Dimension TL measured from maximum HD.

5.

Body contour optional within zone defined by HD, CD, and Q.

6.

Leads at gauge plane .054 +.001 -.000 inch (1.37 +0.03 -0.00 mm) below seating plane shall

be within .007 inch (0.18 mm) radius of true position (TP) at maximum material condition

(MMC) relative to tab at MMC.
