Derating connector current ratings for real-world PCB power designs

January 14, 2026 By Aharon Etengoff Leave a Comment

Many datasheet connector current ratings are based on test conditions that rarely reflect real-world printed circuit board (PCB) power designs. These values typically represent performance in free air at controlled ambient temperatures, with optimal copper distribution and without the thermal constraints imposed by dense board layouts, enclosures, or altitude. Engineers who apply these ratings directly […]
