Notes:
1. Post(s) can be omitted for keying
purposes. 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 on the solder tail.
3. .125 [3.18] solder tail lengths are
for .062 [1.57] thick printed circuit
boards and .175 [4.45] solder tail
lengths are for .093-.125 [2.36-
3.18] thick printed circuit boards.
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].
