Description
50 Ohm Semi-Flexible Coaxial Cable | FEP Jacket | PTFE Dielectric
The ROSNOL RSF-141-FEP is a precision 50 Ω handformable coaxial cable engineered for broadband RF and microwave systems operating from DC to 26.5 GHz. Designed for applications requiring stable electrical performance, repeatable bending, and low loss, this cable delivers a velocity of propagation of 70%, capacitance of 95.2 pF/m, and a signal delay of 4.72 ns/m. Its exceptionally high screening effectiveness of ≥100 dB (up to 18 GHz) ensures excellent EMI immunity, making it suitable for sensitive measurement environments, high-frequency transceiver modules, radar subsystems, and microwave instrumentation.The RSF-141-FEP features a solid steel inner conductor with copper and silver plating for mechanical rigidity and low-resistance current flow. The dielectric is high‑grade PTFE, providing thermal stability and minimal dielectric loss across the broadband spectrum. A tin‑plated copper braid offers robust shielding and mechanical strength, while the FEP outer jacket enhances environmental resistance and long‑term reliability. The cable’s compact 4.10 mm outer diameter and a minimum bending radius of only 9.53 mm allow precise routing in dense layouts and semi‑rigid replacement applications.
The RSF-141-FEP is an ideal solution for precision RF interconnects, custom microwave cable assemblies, space‑constrained layouts, and semiconductor test hardware where repeatable mechanical shaping and stable high‑frequency performance are essential.
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.
