Description
75 Ohm Semi-Flexible Coaxial Cable | Tin-Plated Copper Shield | PTFE Dielectri
The ROSNOL RSF-141-75 is a 75 Ohm semi-flexible coaxial cable optimized for microwave applications up to 18 GHz. It features a silver-plated copper inner conductor (∅0.51 mm / 0.020 in), PTFE dielectric (∅2.995 mm / 0.118 in), and a tin-plated copper shield (∅3.58 mm / 0.141 in). With a minimum bending radius of 8 mm (0.315 in), this cable supports operating temperatures from -65°C to +150°C.Electrical performance includes 65 pF/m capacitance, 70% signal velocity, and 4.7 ns/m signal delay. It offers insulation resistance ≥ 1×10⁸ MΩ/m and screening effectiveness ≥ 100 dB up to 1 GHz. Typical attenuation ranges from 0.29 dB/m at 0.5 GHz to 2.62 dB/m at 18 GHz, with maximum CW power handling of 550 W at lower frequencies. The RSF-141-75 is RoHS compliant and ideal for precision 75 Ohm systems.
