Product details
The 4189 from Keystone Electronics delivers breakthrough performance in Terminal Strips and Turret Boards for quantum computing applications. This cryogenic-rated terminal strip maintains signal integrity at 4K temperatures while minimizing thermal conductivity in dilution refrigerator environments. 4189's unique design addresses the challenges of low-noise measurement and qubit control in quantum processing units.As a Binding Post Strip configuration, this component features superconducting-compatible materials with magnetic permeability <1.01 for quantum interference device (SQUID) applications.Screw Terminal connections utilize oxygen-free copper with rhodium plating to minimize Johnson-Nyquist noise in milliKelvin environments.The 3 channel architecture supports simultaneous qubit control and readout with crosstalk below -90dB.0.437" (11.10mm) spacing prevents parasitic capacitance while allowing for superconducting wire bonding in cryogenic probe stations.Dual 1 design separates DC bias lines from RF microwave drive signals, essential for quantum gate operations.The 2.125" L x 0.625" W x 0.062" H (54.00mm x 15.90mm x 1.57mm) footprint is optimized for standard quantum device packages with ultra-low thermal mass requirements.Made from XP Phenolic substrate, the material exhibits negligible thermal contraction mismatch with silicon qubit chips.Special Standard Strip include gold-plated coaxial transitions and superconducting ground planes for microwave packaging.
