Semi-Flexible Ø2.17 mm (.0854 inch), 25Ω, DC-20GHz

25 Ohm Semi-Flexible Coaxial Cable | Tin-Plated Copper Shield | PTFE Dielectric

The ROSNOL RSF-085C-25 is a 25 Ohm semi-flexible coaxial cable designed for specialized microwave applications up to 20 GHz. It features a silver-plated copper inner conductor (∅0.94 mm / 0.0370 in), PTFE dielectric (∅1.68 mm / 0.0661 in), and a tin-plated copper shield (∅2.17 mm / 0.0854 in). With a minimum bending radius of 6 mm (0.2362 in) and weight of 20 g/m, this cable offers precision performance in compact environments.

Electrical characteristics include 195 pF/m capacitance, 70% signal velocity, and 4.7 ns/m signal delay. It provides insulation resistance ≥ 1×10⁸ MΩ/m and screening effectiveness ≥ 90 dB. Typical attenuation ranges from 0.59 dB/m at 0.5 GHz to 4.32 dB/m at 18 GHz, with maximum CW power handling of 190 W. The RSF-085C-25 is RoHS compliant and supports operating temperatures from -55°C to +150°C.
