NOTES:
1. Index area: A notch or a pin 1 identification mark shall be located adjacent to pin 1 and shall be within the
shaded area shown. The manufacturer's identification shall not be used as a pin 1 identification mark.
Alternatively, a tab (dimension TL) may be used to identify pin 1. This tab may be located on either side as
shown. If a pin 1 identification mark is used in addition to this tab, the minimum limit of dimension TL does
not apply.
2. Dimension LO2 shall be measured at the point of exit of the lead from the body. Dimension LO2 shall be
.0085 inch (0.216 mm) minimum when lead finish A is solder.
3. These dimensions allow for off-center lid, meniscus, and glass overrun.
4. The basic pin spacing is .050 inch (1.27 mm) between centerlines. Each pin centerline shall be located within
±.005 inch (0.13 mm) of its exact longitudinal position relative to pins 1 and 10.
5. All leads: Dimensions are pre-solder dip.
6. Eight spaces.
7. Applies to all four corners (lead numbers 1, 5, 6, and 10).
8. Dimension LO may be .000 inch (0.00 mm) if lead numbers 1, 5, 6, and 10 bend toward the cavity of the
package within one lead width from the point of entry of the lead into the body. For all bottom-brazed or side-
brazed configurations, dimension LO shall be measured from the edge of the furthest extension of the metal
pad or lead.
9. Optional configuration. If this configuration is used, no organic or polymeric materials shall be molded to the
bottom of the package to cover the leads.
10. Dimensions are in inches. Millimeters are given for general information only.
