Product details
The 0395000004 from Molex represents a quantum leap in Terminal Blocks - Headers, Plugs and Sockets technology for quantum computing applications. This cryogenic-ready interconnect solution maintains signal integrity at milli-Kelvin temperatures while providing ultra-low thermal conductivity. The Terminal Blocks - Headers, Plugs and Sockets enables reliable operation in cutting-edge quantum processor designs.Featuring Plug, Female Sockets construction, this component achieves unprecedented thermal performance at cryogenic temperatures. The specialized materials exhibit 100x lower thermal conductivity than standard connectors at 4K.Available in 4 positions, the design supports scalable qubit architectures. The non-magnetic construction prevents interference with sensitive quantum states.With 4 positions per level, the layout minimizes parasitic capacitance between control lines. This arrangement is critical for maintaining qubit coherence times.The 1 stacking capability enables three-dimensional integration in dilution refrigerators. The ultra-compact design maximizes valuable cryostat space.The 0.138" (3.50mm) pitch spacing prevents cross-talk between adjacent microwave control lines. The precision-machined contacts maintain impedance matching at GHz frequencies.180° entry geometry accommodates superconducting cabling. The strain-free termination prevents microphonic effects in sensitive measurements.Utilizing Screw - Rising Cage Clamp termination, the system ensures stable connections during thermal cycling. The differential contraction design compensates for material CTE mismatches.The Free Hanging (In-Line) mounting prevents thermal shorts in cryogenic systems. The G10 isolation standoffs reduce heat leak to milliwatt levels.Rated for 8 A at 4K, the contacts utilize superconducting alloys. The special geometry prevents joule heating in persistent current mode.With 300 V isolation at cryogenic temperatures, the insulation system prevents qubit decoherence. The ultra-pure dielectrics exhibit negligible dielectric loss.Compatible with 16-30 AWG superconducting wires, the termination maintains critical current density. The gold-plated interfaces prevent oxidation in ultra-high vacuum.The Black housing uses specialized low-outgassing materials for vacuum environments. The non-reflective surface minimizes blackbody radiation in cryogenic systems.Operating across -40°C ~ 115°C range, from 300K to 10mK, the materials maintain mechanical stability. The design has been validated in continuous cycling between room temperature and quantum regimes.Tin plating provides optimal performance at cryogenic temperatures. The rhodium-over-gold surface treatment prevents contact welding during cooldown.
