Soldering Parameters
Notes:
1. Dimensioning and tolerances per ANSI 14.5M-1982.
2. Package conforms to EIAJ SC-74 (1992).
3. Dimensions D and E1 are exclusive of mold flash, protrusions, or gate burrs.
4. Footlenth L measured at reference to seating plane.
5. “L” is the length of flat foot surface for soldering to substrate.
6. “N” is the number of terminal positions.
7. Controling dimension: MILLIMETER. Converted inch dimensions are not necessarily
exact.
