** 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.
