37C04-3101-000 FL

The 37C04-3101-000 FL from 3M delivers breakthrough performance in Rectangular Connectors - Free Hanging, Panel Mount for high-reliability computing applications. This precision-engineered interconnect solution is optimized for server backplanes, storage arrays, and network switches, offering exceptional signal integrity at data rates up to 56Gbps.As a Socket solution, it features a unique mezzanine design for vertical stacking of PCBs. The guided mating system ensures accurate alignment in high-density configurations with less than 0.2mm positional tolerance.The Female Socket design incorporates dual-beam geometry with independent contact points. This redundant configuration provides 60% better contact reliability than single-beam designs in vibration tests.Configurable up to 8 contacts, the connector supports various lane configurations for PCIe, SAS, and Ethernet protocols. The numbered keying system prevents incorrect card insertion.The 0.079" (2.00mm) fine-pitch arrangement enables 56G PAM4 signaling with less than -25dB worst-case crosstalk. The ground-signal-ground contact pattern provides optimal return path continuity.The 2 row staggered configuration reduces parallel resonance effects. This layout minimizes impedance discontinuities at high frequencies while maintaining mechanical stability.0.256" (6.50mm) inter-row distance optimizes airflow while maintaining crosstalk performance. This engineered spacing allows for effective cooling in 1U rack configurations.The Free Hanging (In-Line) version includes solder-tail options for both through-hole and surface-mount applications. The precision-molded alignment posts facilitate automated PCB assembly.The Latch Holder mechanism provides both temporary and permanent retention options. The tool-less latch design enables quick card replacement during hot-swap operations.Featuring IDC technology, the system maintains consistent impedance through the transition zone. The graduated strain relief prevents sharp bends within critical signal areas.Compatible with Discrete high-speed cables, the contacts preserve skew within 5ps/m across differential pairs. The controlled-impedance breakout region minimizes mode conversion.Supporting 24-26 AWG configurations, the power contacts deliver up to 3A per pin with less than 30 C temperature rise. The multi-finger design ensures parallel current paths for reduced resistance.The Closed End include integrated ESD protection diodes on critical lines. These devices clamp transient voltages below sensitive component thresholds without adding capacitance.The Black housing material incorporates laser-markable surfaces for permanent identification. The low-dielectric polymer maintains stable electrical properties across temperature variations.
