NOTES:
1. DIMENSIONING AND TOLERANCING PER ANSI
Y14.5M 1982.
2. DATUMPLANE –H– IS LOCATED AT BOTTOMOF LEAD
AND IS COINCIDENT WITH THE LEAD WHERE THE
LEAD EXITS THE PLASTIC BODY AT THE BOTTOMOF
THE PARTING LINE.
3. DATUMS –A–, –B– AND –D– TO BE DETERMINED AT
DATUMPLANE –H–.
4. DIMENSIONS D AND E TO BE DETERMINED AT
SEATING PLANE –C–.
5. DIMENSIONS D1 AND E1 DO NOT INCLUDE MOLD
PROTRUSION. ALLOWABLE PROTRUSION IS 0.25
(0.010) PER SIDE. DIMENSIONS D1 AND B1 DO
INCLUDE MOLD MISMATCH AND ARE DETERMINED
AT DATUMPLANE –H–.
6. DIMENSION b DOES NOT INCLUDE DAMBAR
PROTRUSION. DAMBAR PROTRUSION SHALL NOT
CAUSE THE b DIMENSION TO EXCEED 0.45 (0.018).
