Notes:
1. Post(s) can be omitted for keying pur-
poses. Specify the desired post(s) to
be omitted using the figure to identify
Post No. 1.
2. Gold headers are duplex plated, gold
on mating end of post and tin-lead on
the solder tail.
3. Headers with straight and right-angle
square posts are available upon
request. Minimums may apply.
4. To determine header overall length
(Dim. A), multiply .156 x the number of
posts. Example: .156 x 10 posts equals
1.560 inches [39.62 mm].
