Notes
1. Package dimensions conform to JEDEC MS–029(FA–1).
2. Controlling dimensions: millimeters. Dimensions in inches are shown in parentheses.
3. Dimensions and tolerancing per ANSI Y14.5 – 1982.
4. Datum plane “H” is located at the mold parting line and is coincident with the lead exits the plastic body at bottom
of the parting line.
5. Datums “A–B” and “D” to be determined at datum plane “H”.
6. To be determined at the seating plane “C”.
7. These dimensions to be determined at datum plane “H”. Dimensions “D” and “E” do not include mold protrusion.
Allowable protrusion is 0.25/0.10” per side.
8. Lead width does not include damber protrusion. Allowable damber protrusion shall be 0.08 mm/0.003” total in excess
of this dimension at the maximum material condition. Dambar cannot be located on the lower radius of the foot.
9. Pin numbers start with pin 1 and continue counter-clockwise to pin 208 when viewed from the top.
