Note: PCB trace design may greatly affect temperature rise results in Wire-to-Board Applications.
** Current rating is application dependent and may be affected by the wire rating such as listed in UL-
60950-1. Each application should be evaluated by the end user for compliance to specific safety agency
requirements. The ratings listed in the chart above represents the MAXIMUM current carrying capacity of a
fully loaded connector with all circuits powered using tinned copper conductor stranded wire per Molex test
method based on a 30º C maximum temperature rise over ambient temperature and are provided as a
guideline. Appropriate de-rating is required based on circuit size, ambient temperature, copper trace size
on the PCB, gross heating from adjacent modules/components and other factors that influence connector
performance. Wire size & stranding, tin coated or bare copper wire, wire length & crimp quality are other
factors that influence current rating.

TEST CONDITION
Mate connectors: apply a maximum
voltage of 20 mV and a current of 100
mA. Wire resistance shall be removed
from the measured value.
Mate connectors: apply a voltage of 500
VDC between adjacent terminals and
between terminals to ground.
Mate connectors: apply a voltage of
2200 VAC for 1 minute between
adjacent terminals and between
terminals to ground.
Mate connectors. Measure the
temperature rise at the rated current
after 96 hours, during current cycling (45
minutes ON and 15 minutes OFF per
hour) for 240 hours, and after final 96-
hour steady state.
