Product details
The 1731070083 by Molex revolutionizes D-Sub Connectors performance in high-speed data center applications. Designed for 112G PAM4 signaling, this connector achieves <0.5dB insertion loss at 28GHz while maintaining 100 differential impedance within 5% tolerance.Featuring D-Sub, Combo architecture, the compact design enables 40% higher port density than traditional form factors without compromising thermal management capabilities.The Plug, Male Pins configuration implements edge-coupled differential pairs with controlled skew (<5ps) for precise timing alignment in SerDes applications.21 (17 + 4 Coax or Power) layout incorporates ground-stitching vias that reduce simultaneous switching noise by 22dB in 56Gbps NRZ applications.Precision-molded 2 dielectric body maintains <3% impedance variation across all channels for consistent signal integrity performance.The Through Hole version features solder-tail alignment guides that ensure 0.1mm placement accuracy during reflow processes.Optimized for airflow management, 4 (DC, C) - 21WA4 design reduces pressure drop by 30% compared to conventional cage designs.Signal and Coax or Power (Not Included) implementation uses phosphor bronze alloys with selective gold plating for optimal signal integrity and durability.The Housing/Shell (Unthreaded) system incorporates thermal interface pads that improve heat dissipation by 25% in high-power applications.Our Solder process creates solder joints that withstand 1000 thermal cycles from 0 C to +100 C without degradation.Steel, Tin Plated construction provides 60dB EMI shielding effectiveness up to 40GHz for sensitive RF applications.The Gold surface treatment maintains <15m contact resistance after 10,000 mating cycles in dusty environments.All materials exceed UL94 V-0 requirements while maintaining low smoke generation (<15% opacity).The 5A design incorporates current-sharing topology that reduces joule heating by 40% at full load.Grounding Indents include integrated retimer circuitry that compensates for up to 36dB channel loss at 56Gbps.
