1-86557-4

The 1-86557-4 from TE Connectivity AMP Connectors sets new benchmarks in FFC, FPC (Flat Flexible) Connectors - Contacts performance, specifically developed for 5G infrastructure and millimeter-wave applications. Its innovative design addresses signal integrity challenges at multi-gigahertz frequencies.With Pin architecture, the contact achieves 1.5:1 VSWR up to 40GHz. The genderless option provides unique advantages in modular system designs requiring field-reconfigurable interconnects.The Crimp system incorporates self-adjusting features that compensate for wire ovality. This automatic compensation maintains <3% resistance variation across production batches.Supporting 22-26 AWG conductors, the contact's tuned spring rate prevents fretting corrosion. Test data shows 80% reduction in micro-arcing compared to conventional designs in high-vibration environments.Tin-Lead selection directly impacts insertion loss, with gold-plated versions measuring <0.1dB at 10GHz. The finish also determines the connector's compatibility with various cleaning solvents.The 100.0µin (2.54µm) specification meets IEC 60068-2-11 salt spray requirements. Thinner flash coatings are preferred for high-speed digital applications where skin effect dominates.
