Semi-Flexible Ø4.1 mm (.161 inch) FEP Jacket, 50Ω, DC-26.5GHz

50 Ohm Semi-Flexible Coaxial Cable | FEP Jacket | PTFE Dielectric

The ROSNOL RSF-141-FEP is a 50 Ohm semi-flexible coaxial cable engineered for microwave systems 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 braid (∅3.58 mm / 0.1409 in), enclosed in a flame-resistant FEP jacket (∅4.10 mm / 0.1614 in). The cable supports a minimum bending radius of 9.53 mm (0.375 in) and operates from -40°C to +120°C.

Electrical performance includes 95.2 pF/m capacitance, 70% signal velocity, and 4.72 ns/m signal delay. It provides insulation resistance ≥ 1×10⁸ MΩ/m and screening effectiveness ≥ 90 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. The RSF-141-FEP is RoHS compliant and ideal for high-frequency, flame-retardant applications.
