0.047 Inch Low Loss Semi-Rigid Cable 50 Ohm SR-047C-LL with Low Density PTFE Dielectric

SR-047C-LL is a low-loss 0.047 inch semi-rigid coaxial cable, developed for high-frequency RF and microwave transmission where signal attenuation must be minimized. The cable incorporates a low-density PTFE dielectric, which lowers capacitance and dielectric loss compared with standard PTFE constructions, resulting in improved insertion loss performance at microwave and millimeter-wave frequencies. The internal conductor system uses silver-plated copper for the center conductor, eliminating ferromagnetic materials while maintaining excellent conductivity. A precision copper tube outer conductor forms a continuous shield that protects signals from external interference and preserves impedance stability. Because the copper tube shield can be shaped during installation, SR-047C-LL is widely used for compact RF interconnects, high-frequency test fixtures, instrumentation wiring, and microwave assemblies where reliable signal integrity and reduced attenuation are critical.
