Description
50 Ohm Semi-Rigid Coaxial Cable | Bare Copper Shield | PTFE Dielectric
The ROSNOL RSR-141C is a 50 Ohm semi-rigid coaxial cable designed for microwave applications 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 bare copper tube outer shield (∅3.58 mm / 0.1409 in). With a minimum bending radius of 6.35 mm (0.2500 in), the cable supports operating temperatures from -40°C to +125°C.Electrical specifications include 95.1 pF/m capacitance, 69.5% signal velocity, and shielding effectiveness ≥ 110 dB. Operating voltage is rated up to 1.9 kVrms. Typical attenuation ranges from 0.26 dB/m at 0.5 GHz to 2.15 dB/m at 20 GHz. The RSR-141C is RoHS compliant and suitable for high-frequency RF systems requiring robust shielding and consistent performance.
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.
