Board Fit and Current Budget
The 68021-114HLF: The 3 A per contact rating is the thermal limit at the contact interface; in a dense board with limited airflow, derate to 2.5 A per contact to keep the temperature rise under the UL94 V-0 housing ceiling.
Mating Cycle Life and Contact Finish
The phosphor bronze base material provides good spring properties and resists stress relaxation over temperature.
