NOTES:

1. Dimensions are in inches.

2. Millimeters are given for general information only.

3. Package contour optional within BD and length BL. Heat slugs, if any,

shall be included within this cylinder but shall not be subject to minimum

limit of BD. The BL dimension shall include the entire body including

slugs.

4. Within this zone lead, diameter may vary to allow for lead finishes and

irregularities other than heat slugs.

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

symbology.
