Maximum Current—Maximum cur-
rent rating of .140 MATE-N-LOK
Connectors is limited by the maximum
operating temperature of the housings
which is 105°C and the temperature rise
of the contacts which is 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 inter-
nal resistance to current flow and thus
generates 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 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.
Minimum Wire Lengths for T-Rise vs. Current Testing
Note: If wire lengths used are less than those listed, 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.
