SpeedStack Mezzanine Connector System

Molex SpeedStack Mezzanine Connector System offers a high-density, low-profile solution that delivers data rates up to 40Gbps per differential pair. With mated stack heights of 4mm to 10mm with a 0.80mm pitch, these connectors provide design flexibility for PCB space-constrained applications. The narrow housing design minimizes airflow obstructions and promotes system cooling. Molex SpeedStack Mezzanine Connector System utilizes a split-pad PCB design that allows for electrical tuning performance and provides edge card compatibility. The robust insert-molded wafer design with protected shrouded housing supports the terminal location to improve electrical balance within the signals for low-profile, high-density systems. In addition, a common grounding pin improves electrical performance and minimizes crosstalk.
