Description
50 Ohm Semi-Rigid Coaxial Cable | Copper Shield | PTFE Dielectric
The ROSNOL RSR-250 is a 50 Ohm semi-rigid coaxial cable designed for microwave applications up to 18 GHz. It features a steel inner conductor plated with copper and silver (∅1.63 mm / 0.0642 in), PTFE dielectric, and a solid copper outer shield (∅6.35 mm / 0.2500 in). With a minimum bending radius of 3.2 mm (0.1260 in) and weight of 155.8 g/100m, the cable supports operating temperatures from -40°C to +100°C.Electrical specifications include 95.2 pF/m capacitance and operating voltage up to 3.0 kVrms. Typical attenuation ranges from 0.13 dB/m at 0.5 GHz to 1.31 dB/m at 18 GHz, with maximum CW power handling of 1780 W at lower frequencies. The RSR-250 is RoHS compliant and suitable for high-power RF systems requiring stable performance and robust shielding.
ROSNOL’s cable solutions are precision-engineered to meet the rigorous demands of RF and microwave transmission systems. Manufactured under ISO 9001-certified processes, ROSNOL cables deliver consistent high quality and performance at competitive pricing, making them a reliable alternative to products from leading European and American brands.
