Maximum Current—Maximum
current rating of Mini-Universal
MATE-N-LOK 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.
Printed Wiring Board Conductor
Size—The finished trace conductor
width and thickness should be maxi-
mized to allow for the greatest current-
carrying capacity and heat dissipation.
Mini-Universal MATE-N-LOK connectors
also will withstand the following tests:
Housing Panel Retention—
26 lb. min.
Housing Lock Strength—9 lb. min.
Thermal Shock—–55°C to

105°C
Temperature-Humidity Cycling—
25°C to 65°C at 95 RH
Vibration—10-55-10 cycles per
minute at .06 inch total excursion
Physical Shock—18 drops,
50 G half-sine at 11 milliseconds

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 above were not tested and this chart contains interpolated
and extrapolated values.
Wire-to-Board
Due to the vast differences in trace geometry and printed circuit board configurations, we are unable to provide a
separate current carrying chart for our printed circuit board header products. However, the above Wire-to-Wire charts
may be used as a guideline for headers if the trace width and thickness is equal to the listed wire gauge. For vertical
headers, only 95% of the Wire-to-Wire value should be used. For right-angle headers, only 75% of the Wire-to-Wire
value should be used. The chart values are only a tool for connector selection and will require the customer to fully
test their application.

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.
