Performance
Characteristics
Maximum Current—Maximum cur-
rent rating of Mini-Universal MATE-N-
LOK connectors is limited by the maxi-
mum operating temperature of the hous-
ings which is 105°C including the tem-
perature 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 capabili-
ty 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—6 lb. min.
Thermal Shock— –55°C to + 105°C
Temperature-Humidity Cycling—
25°C to 65°C at 95 RH
Corrosion—48 hr. at 5% salt
concentration
Vibration—10-55-10 cycles per
minute at .06 inch total excursion
Physical Shock—18 drops,
50 G half-sine at 11 milliseconds

Mini-Universal MATE-N-LOK Connectors — Calculated Current Table
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 sep-
arate 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 head-
ers, 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.
