1. DIMENSIONING AND TOLERANCING
PER ANSI Y14.5M, 1982.
2. CONTROLLING DIMENSION:
MILLIMETER.
3. DATUM PLANE −AB− IS LOCATED AT
BOTTOM OF LEAD AND IS COINCIDENT
WITH THE LEAD WHERE THE LEAD
EXITS THE PLASTIC BODY AT THE
BOTTOM OF THE PARTING LINE.
4. DATUMS −T−, −U−, AND −Z− TO BE
DETERMINED AT DATUM PLANE −AB−.
5. DIMENSIONS S AND V TO BE
DETERMINED AT SEATING PLANE −AC−.
6. DIMENSIONS A AND B DO NOT INCLUDE
MOLD PROTRUSION. ALLOWABLE
PROTRUSION IS 0.250 (0.010) PER SIDE.
DIMENSIONS A AND B DO INCLUDE
MOLD MISMATCH AND ARE
DETERMINED AT DATUM PLANE −AB−.
7. DIMENSION D DOES NOT INCLUDE
DAMBAR PROTRUSION. DAMBAR
PROTRUSION SHALL NOT CAUSE THE
D DIMENSION TO EXCEED 0.520 (0.020).
8. MINIMUM SOLDER PLATE THICKNESS
SHALL BE 0.0076 (0.0003).
