(Current ratings are maximum and may vary depending on wire size, circuit count, and end-use
application. Further testing may be required in the end-use application.)
4.2 CURRENT DERATING 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.

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.
