The Molex SpeedStack™ mezzanine connector system provides a low profile solution for PCB space savings and a narrow body width for optimized airflow in high-speed and very dense applications. Compact SpeedStack connectors feature a stack height of 4.00mm and support data rates up to 40 Gbps per differential pair. SpeedStack connectors will be displayed at Molex booth 117, DesignCon 2014.
