172781-2

TE Connectivity AMP Connectors's 172781-2 establishes new standards in Terminals - Wire to Board Connectors solutions for data center infrastructure, optimized for high-speed server backplanes and network switches. This innovative connector system supports 56G PAM4 signaling while providing robust mechanical stability in rack-mounted equipment.The Wire to Board design incorporates differential pair alignment features that maintain <1% skew for high-speed data transmission up to 112Gbps NRZ.Precision 0.047" ~ 0.063" (1.19mm ~ 1.60mm) tolerances ensure impedance-controlled via transitions in 20+ layer server PCBs, minimizing signal reflections.With 0.043" ~ 0.055" (1.10mm ~ 1.40mm) compatibility, the connector supports both shielded twinax and fiber optic breakout cables for flexible data center deployments.The 0.335" (8.50mm) profile has been optimized through 3D electromagnetic simulation to reduce insertion loss below 0.5dB/inch at 28GHz.Supporting 26-30 AWG power conductors, the terminal delivers 100A continuous current with only 10 C temperature rise in forced air cooling scenarios.The Brass alloy provides optimal stress relaxation characteristics for maintaining contact force in high-temperature server environments.Tin surface treatment has been specially formulated to prevent whisker growth in data center humidity conditions while maintaining <10m contact resistance.
