Performance Characteristics
(Continued)
Maximum Current—Maximum cur-
rent rating of .062 Commercial Pin and
Socket connectors is limited by the
maximum operating temperature of the
housings which is 105°C including the
temperature rise of the contacts which is
a maximum of 30°C. There are several
variables which have a direct effect on
this maximum current-carrying capabil-
ity for a given connector and must be
considered for each application. These
variables are:
Wire Size—Larger wire will carry
more current since it has less internal
resistance to current flow and thus gen-
erates less heat. Longer wire lengths
also enhance current-carrying capabili-
ties since the wire conducts heat away
from the connector.
Connector Size—In general, the more
circuits in a connector, the less current
can be carried.
Ambient Temperature—The higher
the ambient temperature, the less cur-
rent can be carried in any given connec-
tor.

Values are based on initial Temperature Rise versus Current Testing and are intended to be a guide in the selection of
a connector family. All applications should be tested by the end user. The values listed are per circuit for fully loaded
housings being 100% energized. Note: All combinations were not tested, and this chart contains interpolated and
extrapolated values.

Note: If wire lengths used are less than those listed above, the current-carry-
ing ability of the system will be reduced due to less heat being conducted
away from the connector. The customer should fully test all applications.
