Product details
The DF1B-28DES-2.5RC from Hirose Electric Co Ltd 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 28 positions, the connector supports 51.2T switch fabrics while maintaining <0.35dB/inch insertion loss at 28GHz.The 0.098" (2.50mm) ultra-low-loss pitch configuration enables 112Gbps NRZ signaling with <1ps skew across 256 differential pairs.The 2-row orthogonal directivity design provides >25dB return loss up to 50GHz for millimeter-wave applications.Optimized 0.098" (2.50mm) spacing prevents mode conversion in 400G CR8 optical engine interfaces while allowing adequate cooling airflow.The Panel Mount, Snap-In version includes integrated heat sinks that dissipate 15W per linear inch without requiring additional airflow.Crimp, IDC 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 White housing material exhibits <0.02 dielectric constant variation from 1-50GHz for consistent signal propagation.
