S44191 is a 50 ohm coaxial cable designed for aerospace and defense applications, featuring a 20 AWG stranded silver-plated copper conductor, PTFE dielectric, and extruded FEP jacket. It has an outer diameter of 0.195 inches (4.95 mm) and operates over a temperature range of -55 to +200°C. The cable includes multilayer shielding with a silver-plated copper flat strip braid, achieving minimum shielding effectiveness of -90 dB. It meets RoHS Directive 2002/95/EC, SAE AS4373E Skydrol resistance, and FAR Part 25.869 flame/smoke requirements. Attenuation at 1 GHz is 11.8 dB/100 ft, and velocity of propagation is 69.5%. The minimum bend radius is 1 inch (25.4 mm).
S44191 is a 50 Ohm coaxial cable and the industry’s workhorse, with decades of proven performance in the aerospace and defense markets. S44191 is equivalent in size as the standard Mil-Spec RG400 coax cable but offers lower loss and improved shielding due to its construction. The construction of the S44191 features a multi-layered shielding that combines conventional shields with an inner braid woven of flat strip of silver plated copper which reduces attenuation at frequencies over 1GHz when compared to round wire braids in standard coaxial cable. The cable VSWR is lower because the braids can be applied more uniformly. The attenuation and VSWR variation due to aging and flexure is substantially less.
