Molex rating is established based on MIL-W-5088 max. current capacity guidelines for
copper conductors and test data summary TS-42815-001 section 5.3.7. Test data is
based on 30 deg. C temperature rise using UL 1015 tinned stranded copper wire.

**PCB trace design may greatly affect temperature rise results.
Ratings shown represent MAXIMUM current carrying capacity of a fully loaded connector
with all circuits powered. Ratings are based on a 30°C maximum temperature rise limit
over ambient (room temperature). Testing conducted with tinned copper conductor
stranded wire. Above charts are intended as a guideline. Current rating is application
dependent. Appropriate de-rating is required depending on factors such as higher ambient
temperature, smaller copper weight of PCB traces, gross heating from adjacent modules
or components and other factors that influence connector performance.

* NOTE: Thermal cycling, vibration and other factors can cause micro-motion within a mated

many factors that may be present in an application, Molex highly recommends the use of lubrication
with Mini-Fit Sr tin-plated terminals for reliability assurance. See AS-42815-001 for more information
