Product details
TE Connectivity Aerospace, Defense and Marine's 228618-2 redefines D-Sub, D-Shaped Connectors - Contacts technology for quantum computing applications. These ultra-precision contacts maintain signal integrity at cryogenic temperatures while minimizing thermal conductivity.Specialized for Coaxial quantum bit control systems, the contacts demonstrate <0.1dB insertion loss at 4K temperatures. Comparative testing shows 50% lower thermal load than conventional cryogenic interconnects.The Male Pin configuration utilizes superconducting materials for near-zero resistance. The patented geometry achieves <10n contact resistance at 10mA bias current.Cryo-optimized Machined technology prevents microphonic noise generation. Each contact undergoes helium leak testing to verify <10^-9 mbar l/s leak rates.Engineered for Coaxial Cable superconducting wiring, the contacts maintain mechanical stability during thermal contraction. Testing confirms <0.01% dimensional change from 300K to 4K.Crimp methods are validated for dilution refrigerator environments. The indium-based system demonstrates 1000+ reliable thermal cycles without performance degradation.Selected Brass composition exhibits near-zero magnetoresistance. Material characterization confirms <1ppm magnetic susceptibility at 10T fields.The Gold surface treatment prevents oxidation in ultra-high vacuum. Auger electron spectroscopy confirms <5 oxide layer after 1000 hours at 10^-10 Torr.With 30.0µin (0.76µm) deposition, the contacts achieve stable thermal emf characteristics. Testing shows <0.1 V/K thermal voltage at cryogenic temperatures.The 8 geometry supports high-density qubit addressing with 50 m pitch capability. Cryogenic SEM imaging confirms zero mechanical deformation at 4K operating temperatures.
