Performance
Characteristics
Maximum Current—Maximum cur-
rent rating of Universal MATE-N-LOK
connectors is limited by the maximum
operating temperature of the housings
which is 125°C for 94V-2 housings and
120°C for 94V-0 housings 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 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.
Universal MATE-N-LOK connectors also
will withstand the following tests:
Vibration—10-55-10 cycles per
minute at .06 inch total excursion
Physical Shock—18 drops, 50 G
sawtooth at 10 milliseconds
Housing Panel Retention—
75 lb. min.
Housing Lock Strength—30 lb. min.
Thermal Shock— -55°C to +85°C
Temperature-Humidity Cycling—
25°C to 65°C at 95 RH
Corrosion—48 hr. at 5% salt
concentration

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 load-
ed housings being 100% energized. Note: All combinations 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.

conducted away from the connector. The customer should fully test
all applications.
