BB3-04BF

Designed for quantum computing environments, Eaton - Electronics Division's BB3-04BF achieves unprecedented performance in Terminal Blocks - Accessories applications. Its cryogenic-compatible construction maintains contact resistance stability from 300K down to 4K with less than 5% variation.The Cover variant utilizes superconducting niobium-titanium alloys that transition below 9.3K, enabling zero-resistance connections in dilution refrigerator applications.With 4 filtered feedthroughs, this solution delivers 80dB attenuation at 10GHz while preserving qubit coherence times above 100 s.When paired with A3, LP3 Series, the assembly demonstrates negligible thermal conductance (<1 W/K) while supporting 1000+ coaxial connections in quantum processor packaging.The Black anodization provides effective thermal radiation shielding while maintaining ultra-high vacuum compatibility below 10^-9 Torr.
