NOTES:

1 DIMENSIONING AND TOLERANCING PER ANSI

Y14.5M, 1982.

2 CONTROLLING DIMENSION: MILLIMETER.

3 DATUM PLANE –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 –L–, –M– AND –N– TO BE DETERMINED

AT DATUM PLANE –H–.

5 DIMENSIONS S AND V TO BE DETERMINED AT

SEATING PLANE –T–.

6 DIMENSIONS A AND B DO NOT INCLUDE MOLD

PROTRUSION. ALLOWABLE PROTRUSION IS

0.25 (0.010) PER SIDE. DIMENSIONS A AND B DO

INCLUDE MOLD MISMATCH AND ARE

DETERMINED AT DATUM PLANE -H-.

7 DIMENSION D DOES NOT INCLUDE DAMBAR

PROTRUSION. DAMBAR PROTRUSION SHALL

NOT CAUSE THE LEAD WIDTH TO EXCEED 0.46

(0.018). MINIMUM SPACE BETWEEN

PROTRUSION AND ADJACENT LEAD OR

PROTRUSION 0.07 (0.003).
