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 b DOES 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.
