640607 datasheet(48/84 Pages) MACOM

48 / 84 page

Material and Finish

Housing — UL94V-0 rated, polyester,

white

Posts — Copper alloy, tin plated,

.000030 [0.00076] or .000015

[0.00038] gold over nickel

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].

For mateability options, see

matrix on pages 34, 35, 54

and 58.

For mating half visuals, use

connectors with a locking ramp

for polarization/retention pur-

poses, see pages 36 thru 39,

55, 60 and 62.

For polarizing purposes only

use connectors without a lock-

ing ramp. See pages 36 thru

39, 55, 60 and 62.

Header Ordering

Information

The “Base Part Numbers”

Chart at right shows the base

part number and number of

posts available for the

described headers.

Prefixes and suffixes are deter-

mined by the number of post

positions in the header. For

example, the complete part

number for a 10-position header

with square posts and a .125

[3.18] solder tail length would be:

Base number 641208 plus

prefix-and-suffix

4- — -0

The correct ordering number is

4-641208-0
