Description
50 Ohm Semi-Rigid Coaxial Cable | Copper Shield | PTFE Dielectric
The ROSNOL RSR-141 is a 50 Ohm semi-rigid coaxial cable engineered for microwave systems up to 26.5 GHz. It features a steel inner conductor plated with copper and silver (∅0.92 mm / 0.0362 in), PTFE dielectric, and a solid copper outer shield (∅3.58 mm / 0.1409 in). With a minimum bending radius of 1.92 mm (0.0756 in) and weight of 49.4 g/100m, the cable supports operating temperatures from -40°C to +120°C and outer conductor integrity up to 175°C.Electrical performance includes 95.2 pF/m capacitance and operating voltage up to 1.9 kVrms. Typical attenuation ranges from 0.25 dB/m at 0.5 GHz to 2.50 dB/m at 26.5 GHz, with maximum CW power handling of 600.4 W. The RSR-141 is RoHS compliant and ideal for high-power RF transmission systems requiring robust shielding and thermal reliability.
ROSNOL’s cable solutions are precision-engineered to meet the rigorous demands of RF and microwave transmission systems. Manufactured under ISO 9001-certified processes, ROSNOL cables deliver consistent high quality and performance at competitive pricing, making them a reliable alternative to products from leading European and American brands. All ROSNOL cables are fully compliant with global environmental and safety regulations, including RoHS and REACH.
