Description
75 Ohm Semi-Rigid Coaxial Cable | Copper Shield | PTFE Dielectric
The ROSNOL RSR-141-75 is a 75 Ohm semi-rigid coaxial cable designed for microwave applications up to 20 GHz. It features a silver-plated copper inner conductor (∅0.51 mm / 0.020 in), PTFE dielectric (∅2.995 mm / 0.118 in), and a solid copper outer shield (∅3.58 mm / 0.141 in). With a minimum bending radius of 15 mm (0.5906 in), the cable supports operating temperatures from -55°C to +125°C.Electrical specifications include 65 pF/m capacitance and operating voltage up to 2 kVrms. Typical attenuation ranges from 0.28 dB/m at 0.5 GHz to 2.21 dB/m at 20 GHz, with maximum CW power handling of 549 W at lower frequencies. The RSR-141-75 is RoHS compliant and suitable for precision 75 Ohm RF systems requiring stable performance and high shielding integrity.
