PACKAGE DIMENSIONS
NOTES:
1. Dimensions are in inches. Millimeters are given for information only.
2. Package contour optional with BD and length BL. Slugs, if any, shall
be included within this cylinder length but shall not be subject to
minimum limit of BD.
3. Lead diameter not controlled in this zone to allow for flash, lead finish
build-up, and minor irregularities other than slugs.
4. In accordance with ASME Y14.5M, diameters are equivalent to Φx
symbology.
