86561-6

The 86561-6 by TE Connectivity AMP Connectors revolutionizes FFC, FPC (Flat Flexible) Connectors - Contacts technology with its cutting-edge design for quantum computing applications. Engineered to maintain signal coherence at cryogenic temperatures, this contact sets new standards for ultra-low noise performance.Featuring Pin geometry, the contact achieves <0.5pF parasitic capacitance while maintaining 10N retention force. Its superconducting-compatible design prevents thermal electromotive forces in sub-Kelvin environments.Utilizing Crimp methodology, the connection exhibits <0.1m resistance drift during thermal cycling. The cold-welding compatible surface finish ensures stable performance in vacuum environments.Designed for 22-26 AWG superconducting wires, the contact's beryllium copper alloy maintains spring properties at 4K. This specialized material selection prevents brittleness in cryogenic conditions.The Gold plating demonstrates <1nV/K thermoelectric coefficient, critical for quantum measurement systems. Gold-cobalt alloys show particular advantages in reducing Johnson-Nyquist noise.With 15.0µin (0.38µm) deposition control, the contact maintains <0.05 in surface roughness for consistent tunneling current. Thinner finishes are preferred to minimize electron scattering in qubit applications.
