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].
