3. DATUM PLANE -H- IS LOCATED AT BOTTOM OF LEAD AND IS
PLASTIC BODY AT THE BOTTOM OF THE PARTING LINE.
5. DIMENSIONS S AND V TO BE DETERMINED AT SEATING PLANE -C-.
6. DIMENSIONS A AND B DO NOT INCLUDE MOLD PROTRUSION. ALLOWA
PROTRUSION IS 0.25 (0.010) PER SIDE. DIMENSIONS A AND B DO INCLUD
MOLD MISMATCH AND ARE DETERMINED AT DATUM PLANE
7. DIMENSION D DOES NOT INCLUDE DAMBAR PROTRUSION. ALLOWABL
DAMBAR PROTRUSION SHALL BE 0.08 (0.003) TOTAL IN EXCESS OF THE D
DIMENSION AT MAXIMUM MATERIAL CONDITION. DAMBAR CANNOT BE
