0.047" Semi-Rigid Coaxial Cable 50 Ohm UT-047 Alternative RF Cable for Test Fixtures

This SR-047 0.047 inch (1.19mm) semi rigid coaxial cable serves as a direct UT-047 alternative, featuring seamless copper tube construction that provides 100% RF shielding with effectiveness exceeding 100 dB. The center conductor utilizes silver-plated copper-clad steel (SCCS) at 0.0113 inch (0.287mm) diameter, delivering excellent conductivity while maintaining mechanical strength for permanent forming. PTFE dielectric supports 70% velocity of propagation with capacitance of 29 pF/ft (95.2 pF/m). Operating frequency extends to 109 GHz, with insertion loss of 10.6 dB/m at 40 GHz and 9.39 dB/m at 65 GHz. MIL-C-17/151 compliant with 3000V RMS voltage rating and RoHS certified, this UT-047 alternative semi rigid cable is suitable for test fixture internal wiring, probe card interconnects, and microwave module integration where phase stability and repeatable performance are required.
