1 DIMENSIONING AND TOLERANCING PER ANSI
Y14.5M, 1982.
2 CONTROLLING DIMENSION: MILLIMETER.
3 DIMENSIONS D AND E DO NOT INCLUDE MOLD
FLASH OR PROTRUSIONS AND ARE MEASURED
AT THE PARTING LINE. MOLD FLASH OR
PROTRUSIONS SHALL NOT EXCEED 0.15 (0.006)
PER SIDE.
4 TERMINAL NUMBERS ARE SHOWN FOR
REFERENCE ONLY.
