Maximum Current—Maximum cur-
rent rating of .093 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
capability for a given connector and
must be considered for each application.
These variables are:
Wire Size—Larger diameter wire will
carry more current since it has less
internal resistance to current flow and
thus generates less heat. Longer wire
lengths also enhance current-carrying
capabilities 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 current
can be carried in any given connector.

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-
carrying ability of the system will be reduced due to less heat being
conducted away from the connector. The customer should fully test
all applications.
