solder contacts
Machined copper alloy contacts in a full range of sizes, with closed
entry socket design in the size 12 and 16 contacts. A heavy silver-
plated finish is deposited on all MS style solder contacts for maximum
corrosion resistance, maximum current carrying capacity and low milli-
volt drop.

* The values listed in Table I represent operating values which include a
generous safety factor. It may be necessary for some applications to
exceed the operating voltages listed here. If this is necessary, designers
will find Table II useful for determining the degree to which the recom-
mended values of Table I can be exceeded.
