Product details
TE Connectivity AMP Connectors introduces the 1888669-5, a breakthrough Memory Connectors - Inline Module Sockets solution for quantum computing applications. This cryogenic-ready connector enables reliable operation at milli-Kelvin temperatures for qubit control systems.Quantum-optimized DIMM architecture minimizes thermal conductivity while maintaining 50 impedance matching at 4K temperatures.The 240 configuration supports microwave signal distribution with <0.01dB crosstalk at 10GHz, critical for superconducting qubit control.Designed for DDR2 SDRAM compatibility, the connector exhibits <1fA leakage current at 10mK for error-free quantum error correction circuits.Beyond MO-237 requirements, the design passes 1000+ thermal shock cycles between 300K and 4K without mechanical failure.The Through Hole implementation utilizes non-magnetic materials with <1ppm/K thermal expansion coefficient matching for dilution refrigerator installations.Specialized Board Lock, Latches include superconducting RF filters that suppress noise above 60dB in the 5-8GHz qubit operating band.Normal, Standard - Top configuration enables vertical integration with quantum processor packages while minimizing vibrational coupling.Cryogenic Gold maintains <5m contact resistance at 4K temperatures with zero thermoelectric voltage generation.Atomic-layer-deposited 15.0µin (0.38µm) coating prevents oxidation while ensuring consistent performance during repeated thermal cycling.
