H4FF4R

Amphenol Industrial Operations's H4FF4R represents a quantum leap in Photovoltaic (Solar Panel) Connectors - Contacts technology for quantum computing applications. The cryogenic-rated design maintains superconducting properties at 4K while providing ultra-low thermal conductivity. This solution enables reliable qubit control signal transmission in dilution refrigerator environments.The Socket configuration features niobium-titanium alloy contacts for zero-resistance performance. Unlike conventional connectors, this implementation maintains <10n contact resistance at millikelvin temperatures.Engineered for 10-12 AWG superconducting wires, the contact system prevents thermal leakage. The innovative clamping mechanism achieves <1 W/K thermal load while maintaining 50 impedance matching.Utilizing Crimp technology, the system achieves ultra-high vacuum compatibility. This critical feature maintains <10-9 Torr vacuum integrity in quantum processor enclosures.The Tin surface treatment prevents cooper pair breaking in superconducting states. The atomically smooth finish (<5nm Ra) minimizes quasiparticle generation in qubit control lines.
