Product Description
The SR-034-SP 0.034 inch (0.86mm) semi-rigid coaxial cable features a silver plated copper clad steel (SCCS) center conductor and silver plated copper tube outer conductor, which makes it a UT-034-SP compatible alternative. The SCCS center conductor provides excellent mechanical strength for permanent forming while maintaining high conductivity. The silver plated copper tube outer conductor enhances solderability, improves corrosion resistance, and ensures consistent surface conductivity for reliable terminations. The seamless tube construction delivers 100% RF shielding with effectiveness exceeding 120 dB, while the PTFE dielectric provides 70% velocity of propagation with 95.2 pF/m capacitance and ±1.5 Ohm impedance tolerance. With 155 GHz higher order mode frequency and 2100V RMS voltage withstanding, this RF coax supports demanding aerospace, defense, and test applications where reliable soldering and environmental resistance are required.
