Description
50 Ohm Semi-Flexible Coaxial Cable | Tin-Plated Copper Shield | PTFE Dielectric
The ROSNOL RSF-047 is a 50 Ohm semi-flexible coaxial cable engineered for high-frequency microwave applications up to 65 GHz. It features a steel inner conductor plated with copper and silver (∅0.287 mm / 0.0113 in), surrounded by a PTFE dielectric and a tin-plated copper outer shield (∅1.14 mm / 0.0449 in). With a compact form factor and hand-formable construction, this cable supports a minimum bending radius of 4 mm (0.1575 in) and weighs only 6.6 g/m. It operates at voltages up to 1.0 kVrms and maintains insulation resistance ≥ 1×10⁸ MΩ/m.Electrical performance includes 95.2 pF/m capacitance, 70% signal velocity, and 4.7 ns/m signal delay. The RSF-047 offers excellent screening effectiveness ≥ 100 dB up to 18 GHz. Typical attenuation ranges from 0.98 dB/m at 0.5 GHz to 12.93 dB/m at 65 GHz, with maximum CW power handling of 73 W at lower frequencies. The cable is RoHS compliant and supports a wide operating temperature range from -65°C to +150°C.
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. Customization services for materials, shielding, and mechanical design are available to support specialized application requirements.
