20021444-00008T4LF

The 20021444-00008T4LF by Amphenol ICC (FCI) revolutionizes Rectangular Connectors - Free Hanging, Panel Mount technology, specifically engineered for next-generation data center infrastructure. This high-speed interconnect solution delivers unparalleled signal integrity for 400G Ethernet and PCIe Gen5 applications, featuring impedance-controlled design and advanced crosstalk mitigation.As a Receptacle solution, it incorporates air-flow optimized housing for improved thermal management. The unique lattice structure reduces airflow restriction while maintaining structural integrity in high-density server configurations.The Female Socket design utilizes elliptical beam geometry that reduces insertion force by 40% compared to conventional designs. The multi-point contact system ensures stable impedance across the entire mating interface.Available in 8 configurations, this modular system supports flexible lane partitioning for various protocol requirements. The symmetrical contact arrangement enables bi-directional signal routing without performance degradation.The 0.050" (1.27mm) micro-pitch configuration enables 112G PAM4 signaling with minimal insertion loss. The precision-molded dielectric material maintains consistent characteristic impedance across the entire connector length.The 2 row architecture incorporates ground shields between each differential pair. This arrangement provides 30dB better near-end crosstalk performance than conventional designs.0.050" (1.27mm) inter-row distance optimizes electromagnetic field containment. This carefully engineered spacing prevents mode conversion in high-speed differential pairs.The Free Hanging (In-Line) version features tool-less PCB retention for quick serviceability. The integrated alignment pins ensure accurate mating during blind-mate cabinet installations.Featuring IDC technology, the system maintains return loss below -30dB up to 28GHz. The controlled-impedance transition region minimizes signal reflection at the cable-connector interface.Compatible with Ribbon Cable twinax cables, the contacts preserve the cable's differential impedance within 5% tolerance. The strain relief system accommodates up to 10N/mm cable bending stress.Supporting 30 AWG coaxial configurations, the contacts exhibit less than 0.2dB insertion loss per contact at 28GHz. The precision crimp profile maintains consistent RF performance across all terminations.The Feed Through include integrated heat sinks for power contact cooling. These thermal management features enable continuous current carrying capacity up to 15A per contact.The Gold plating exceeds IEC 60512-99-001 fretting corrosion requirements. The selective gold plating on contact points reduces material costs without compromising performance.With 10.0µin (0.25µm) gold plating, the contacts achieve less than 2m contact resistance after 500 mating cycles. The nickel barrier layer prevents copper diffusion at elevated temperatures.The Black housing material incorporates 30% glass fiber reinforcement for dimensional stability. The high-temperature resistant polymer maintains mechanical properties up to 150 C.
