Description
50 Ohm Semi-Flexible Coaxial Cable | Tin-Plated Copper Shield | PTFE Dielectric
The ROSNOL RSF-141 is a 50 Ohm semi-flexible 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 tin-plated copper shield (∅3.58 mm / 0.1409 in). With a minimum bending radius of 9.53 mm (0.375 in) and weight of 43 g/m, this cable offers excellent mechanical stability and thermal performance from -40°C to +120°C.Electrical specifications include 95.2 pF/m capacitance, 70% signal velocity, and 4.7 ns/m signal delay. It provides insulation resistance ≥ 1×10⁸ MΩ/m and screening effectiveness ≥ 100 dB up to 18 GHz. Typical attenuation ranges from 0.30 dB/m at 0.5 GHz to 2.95 dB/m at 26.5 GHz, with maximum CW power handling of 491.7 W at lower frequencies. The RSF-141 is RoHS compliant and suitable for high-frequency interconnects.
