Product details
The 770849-4 from TE Connectivity AMP Connectors sets new standards in Rectangular Connectors - Housings for hyperscale data centers. Its high-density architecture supports 400G Ethernet and PCIe Gen5 while optimizing thermal management.The Receptacle design incorporates novel airflow channels that reduce thermal resistance by 40% compared to conventional high-speed connectors.Optimized Female Socket contacts feature elliptical cross-sections that minimize skin effect losses at 56GHz, critical for 112G PAM4 signaling.With 4 positions, the connector supports 51.2T switch fabrics while maintaining <0.35dB/inch insertion loss at 28GHz.The 0.156" (3.96mm) ultra-low-loss pitch configuration enables 112Gbps NRZ signaling with <1ps skew across 256 differential pairs.The 1-row orthogonal directivity design provides >25dB return loss up to 50GHz for millimeter-wave applications.The Free Hanging (In-Line) version includes integrated heat sinks that dissipate 15W per linear inch without requiring additional airflow.Crimp technology creates impedance-controlled transitions with <5% variation across entire connector length.The Locking Ramp system provides precise coplanarity (<50 m) across 400+ contacts required for large ASIC packages.The Natural housing material exhibits <0.02 dielectric constant variation from 1-50GHz for consistent signal propagation.Featuring Polarizing Key, the connector achieves 70 pitch alignment accuracy while supporting 3D wafer-scale packaging integration.
