1. Dimensioning and tolerancing per Ansi
Y14.5-M, 1982
2. Controlling dimension: Millimeter
3. Datum Plane "H" is located at the
bottom of the 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 -H-.
5. Dimensions S and V to be determined
at seating plane -C-.
6. Dimensions A and B do not include
Mold protusion. Allowable protusion
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 Danbar
protrusion. Allowable Danbar
protrusion is 0.08 (0.003) total in
excess of the D dimension
at Maximum Material Condition.
