3.2 CURRENT AND APPLICABLE WIRES
(Current is dependent on connector size, contact
material, plating, ambient temperature, printed circuit board characteristics and related factors.
Actual current rating is application dependent and should be evaluated for each application.
Maximum current assuming PCB trace size is equivalent to the following wire sizes:
AWG

*including terminal temperature rise. Testing of the housing material to establish the maximum
operating temperature for the connector assembly at UL is in progress. The currently assigned
maximum operating temperature rating at UL is 65°C and is the default rating for the material.
This rating is expected to be increased to 105°C upon completion of the in-progress product
safety tests.

TEST CONDITION
Mate connectors: apply a maximum voltage
of 20 mV and a current of 100 mA.
Terminate the applicable wire to the terminal
and measure wire using a voltage of 20 mV
and a current of 100 mA.
Unmate & unmount connectors: apply a
voltage of 500 VDC between adjacent
terminals and between terminals to ground.
Unmate connectors: apply a voltage of {two
times the rated voltage plus 1000 volts} VAC
for 1 minute between adjacent terminals and
between terminals to ground.
Measure between adjacent terminals at 1
MHz.
Mate connectors: measure the temperature
rise at the rated current after:
1) 96 hours (steady state)
2) 240 hours (45 minutes ON and 15
minutes OFF per hour)
3) 96 hours (steady state)
