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