The 5028A3318-9 is a high-performance, 28 AWG coaxial cable designed for 50-ohm impedance systems. Its construction features a 7-strand, silver-coated copper-clad steel conductor, a Rayfoam L dielectric, and robust dual AWG 38 silver-coated copper shields, each providing at least 90% coverage. The cable exhibits a nominal capacitance of 27.8 pF/ft and a velocity of propagation of 73%. Encased in a durable white Thermorad S jacket as designated by the '-9' suffix, it is engineered to perform in harsh conditions, withstanding heat shock at 225°C and cold bend tests at -55°C. This makes it ideal for use in demanding applications requiring reliable high-frequency signal transmission.
