5204-0021-90

The 5204-0021-90 by Leader Tech Inc. represents a quantum leap in Circular Connectors - Accessories for quantum computing applications. This cryogenic-ready accessory maintains signal fidelity at temperatures approaching absolute zero while preventing thermal leakage in superconducting circuits.Functioning as EMI Gasket, this revolutionary design exhibits less than 0.1dB insertion loss at 4K temperatures. Its non-metallic construction eliminates eddy current losses in high-field MRI environments.Optimized for MIL-DTL-26482, MIL-DTL-5015, MIL-DTL-83723 Flange Connector, the accessory demonstrates zero outgassing in ultra-high vacuum (10^-9 Torr) conditions. Materials selection follows NASA outgassing standards for space applications.Engineered to 20 specifications with 0.001 tolerance, the component prevents thermal shorts in multi-stage cryocooler systems. The nanoscale surface finish minimizes heat conduction through mechanical contacts.The cryogenic Fluorosilicone, Nickel Coated Graphite Filled composite maintains dimensional stability across 300K to 4K thermal cycles. Material testing confirms no embrittlement after 1000 cycles between room temperature and liquid helium temperatures.Featuring Square, this solution provides ultra-low thermal conductivity (<0.1 W/mK) while maintaining 100Gbps data transmission. Its monolithic construction eliminates differential contraction issues in cryogenic environments.
