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). Above charts are intended as a guideline. Current rating is application dependent.
Appropriate de-rating is required depending on factors such as circuit size, ambient temperature,
smaller copper weight of PCB traces, gross heating from adjacent modules or components and other
factors that influence connector performance. Wire size and stranding, tin coated or bare copper, wire
length and crimp quality are other factors that influence current rating. Current ratings apply to Brass
5556 crimp terminals only.
