1663533-5

TE Connectivity Aerospace, Defense and Marine's 1663533-5 sets the benchmark in Backplane Connectors - Contacts for data center infrastructure. Designed for high-density server applications, this connector supports 112G PAM4 signaling with excellent return loss characteristics below -30dB up to 16GHz.The Power implementation features patented crosstalk cancellation technology that improves signal-to-noise ratio by 15dB. System architects benefit from its backward compatibility with existing 56G NRZ architectures.Featuring Pin configuration with anti-stubbing design, the connector enables blind mating in rack-mounted equipment. The floating contact mechanism compensates for 0.5mm alignment tolerances.The Solder process utilizes laser-cleaned surfaces prior to termination, achieving oxide-free connections. This method reduces insertion loss variation to less than 0.1dB across 10,000 mating cycles.Gold surface treatment incorporates nanoscale roughness control for optimal signal reflection. Measurements confirm surface roughness (Ra) remains below 0.1 m throughout the product lifecycle.Precision-controlled 50.0µin (1.27µm) deposition achieves skin depth optimization at 28GHz. The thickness uniformity is verified through automated optical inspection with 99.9% process capability.
