Product details
The 0857891003 by Molex introduces innovative Modular Connectors - Jacks With Magnetics technology for quantum computing systems. This ultra-low noise connector solution combines cryogenic performance with precision signal integrity, enabling reliable operation in superconducting quantum processors. The specialized materials minimize thermal conductivity while maintaining excellent RF characteristics.The RJ45 interface features non-magnetic components with <0.01% magnetic susceptibility, critical for qubit coherence in 10mK environments.With 1 isolated channels, this configuration enables simultaneous control and readout of multiple qubits without signal degradation.The 1 row arrangement minimizes parasitic capacitance (<0.1pF) between adjacent microwave lines in quantum processor interconnects.Optimized for 10/100/1000 Base-T, AutoMDIX, Power over Ethernet+ (PoE+) quantum computing implementations, this connector maintains <0.05dB insertion loss at 4K temperatures.The Through Hole installation method withstands repeated thermal cycling between 300K and 10mK without mechanical failure.90° Angle (Right) PCB alignment facilitates optimal signal routing in dilution refrigerator stack configurations.Utilizing Solder technology, the contact system achieves <0.5m resistance at cryogenic temperatures with minimal thermal load.The 0.546" (13.87mm) profile allows proper clearance for multi-layer thermal shielding in cryogenic systems.Green, Orange - Green indicators feature cold-tolerant LEDs operable down to 4K for system status monitoring.The 8-core architecture supports simultaneous DC bias and RF control lines for superconducting qubits.Shielded, EMI Finger effectiveness exceeds 100dB at 10GHz, critical for preventing microwave crosstalk between qubit control channels.Incorporating Board Lock, this connector provides integrated thermal breaks to minimize heat leakage into cryogenic stages.The Up latching mechanism operates reliably at cryogenic temperatures without embrittlement.Phosphor Bronze contacts exhibit negligible thermal conductivity while maintaining excellent electrical properties at 4K.The Gold plating process creates a surface stable under ultra-high vacuum (10-9 torr) conditions.Rated for 0°C ~ 70°C operation, this component maintains performance from room temperature to millikelvin regimes.
