Product details
The 0743370072 by Molex revolutionizes D-Shaped Connectors - Centronics for high-speed digital systems. This 112G PAM4 optimized connector family delivers unprecedented signal integrity for 400G Ethernet and AI accelerator applications, reducing jitter to sub-picosecond levels in hyperscale data center environments.Featuring Outer Shroud Contacts geometry, this design implements patented dielectric structures that reduce insertion loss to 0.3dB/inch at 56GHz for next-gen server interconnects.Available in Stacked, 2 Receptacles variants, these connectors support 112Gbps PAM4 signaling with less than 5% UI deterministic jitter in switch fabric backplanes.With 68, 68 differential pairs, this series enables 51.2Tbps aggregate bandwidth for AI/ML training clusters and computational storage systems.The 2 row staggered configuration provides 70dB near-end crosstalk isolation, exceeding IEEE 802.3ck requirements for 800G Ethernet implementations.Through Hole, Right Angle options include press-fit versions that maintain 100 differential impedance tolerance within 5% for high-speed PCB designs.Utilizing Solder technology, these connectors achieve 15 m maximum pad coplanarity for reliable surface mount assembly in automated PCB production lines.The Mating Side (M2) design incorporates precision guide pins that maintain alignment tolerances below 50 m for error-free blind mating in rack-scale systems.As a SCSI+, VHDCI specialist, this series implements embedded equalization that compensates for skin effect losses at millimeter-wave frequencies.Critical Board Lock, Cover, Shielded include integrated heat sinks and airflow optimization for thermal management in high-power compute accelerators.The Gold surface treatment combines low insertion loss characteristics with 1,000 mating cycle durability in hot-swappable server applications.Nano-scale controlled Flash ensures consistent impedance profiles across all contacts for multi-lane timing synchronization.
