265A61-12

Designed for quantum computing environments, Curtis Industries's 265A61-12 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 12 filtered feedthroughs, this solution delivers 80dB attenuation at 10GHz while preserving qubit coherence times above 100 s.When paired with CDM 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.
