Description
50 Ohm Semi-Rigid Coaxial Cable | Tin-Plated Copper Shield | PTFE Dielectric
The ROSNOL RSR-141-TP is a 50 Ohm semi-rigid coaxial cable engineered to MIL-DTL standards, optimized for microwave systems up to 26.5 GHz. It features a silver-plated copper weld inner conductor (∅0.92 mm / 0.036 in), PTFE dielectric (∅2.99 mm / 0.118 in), and a tin-plated copper outer shield (∅3.58 mm / 0.141 in). With a minimum bending radius of 6.35 mm (0.250 in), the cable supports operating temperatures up to 125°C.Electrical performance includes 95.2 pF/m capacitance, 69.5% signal velocity, and shielding effectiveness ≥ 165 dB. Operating voltage is rated at 1900 Vrms. Typical attenuation ranges from 0.25 dB/m at 0.5 GHz to 2.50 dB/m at 26.5 GHz, with maximum CW power handling of 600.4 W. The RSR-141-TP is RoHS compliant and ideal for high-power RF transmission systems requiring military-grade reliability.
