NOTES:
1. DIMENSIONS AND TOLERANCING PER ANSI
Y14.5M, 1982.
2. CONTROLLING DIMENSION: MILLIMETER.
3. DATUM PLANE DATUM H 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 A, B AND D TO BE DETERMINED AT
DATUM PLANE DATUM C.
5. DIMENSIONS D AND E TO BE DETERMINED AT
SEATING PLANE DATUM C.
6. DIMENSIONS D1 AND E1 DO NOT INCLUDE
MOLD PROTRUSION. ALLOWABLE PROTRUSION
IS 0.25 PER SIDE.
7. DIMENSION bDOES NOT INCLUDE DAMBAR
PROTRUSION. DAMBAR PROTRUSION SHALL
NOT CAUSE THE b DIMENSION TO EXCEED 0.35.
MINIMUM SPACE BETWEEN PROTRUSION AND
ADJACENT LEAD OR PROTRUSION 0.07.
