Description
50 Ohm Semi-Rigid Coaxial Cable | Copper-Tin-Zinc Alloy Shield | PTFE Dielectric
The ROSNOL RSR-085-CTZ is a 50 Ohm semi-rigid coaxial cable optimized for microwave applications up to 61 GHz. It features a steel inner conductor plated with copper and silver (∅0.53 mm / 0.0209 in), PTFE dielectric (∅1.68 mm / 0.0661 in), and a copper-tin-zinc alloy plated outer shield (∅2.20 mm / 0.0866 in). With a minimum bending radius of 7.63 mm (0.3004 in) and weight of 21.3 g/100m, the cable supports operating temperatures from -55°C to +125°C and outer conductor integrity up to 175°C.Electrical specifications include 95.1 pF/m capacitance and operating voltage up to 1.5 kVrms. Typical attenuation ranges from 0.45 dB/m at 0.5 GHz to 3.29 dB/m at 20 GHz, with maximum CW power handling of 190.3 W. The RSR-085-CTZ is RoHS compliant and suitable for high-frequency systems requiring robust shielding and thermal reliability.
