Product details
The L829-1J1T-JM by Bel Fuse Inc. 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 2.5G Base-T, AutoMDIX quantum computing implementations, this connector maintains <0.05dB insertion loss at 4K temperatures.The Board Edge, 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 0.440" (11.18mm) profile allows proper clearance for multi-layer thermal shielding in cryogenic systems.Yellow - Green, Orange indicators feature cold-tolerant LEDs operable down to 4K for system status monitoring.The 4-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 Guide, this connector provides integrated thermal breaks to minimize heat leakage into cryogenic stages.The Up latching mechanism operates reliably at cryogenic temperatures without embrittlement.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.
