RG 303 U

RG 303 U — RG Coaxial Cable

Our RG 303 U is a specialized coaxial cable designed for high-frequency applications. With an approximate weight of 30 pounds per thousand feet (LBS/MFT), this cable offers a balance of durability and flexibility. The conductor material is silver-coated copper-clad steel, combining the conductivity of copper with the strength of steel. The conductor stranding is solid, providing a stable signal transmission. The cable features a dielectric material made of Polytetrafluoroethylene (PTFE), known for its low loss and high dielectric strength. It has a dielectric thickness of 0.116 inches. The jacket material is made of Fluorinated Ethylene Propylene (FEP), which provides durability, resistance to heat, and chemical properties. The cable can operate in a temperature range from -55 degrees Celsius (Min. Temp) to 200 degrees Celsius (Max. Temp), making it suitable for extreme environments. It has a single strand as the conductor, with a nominal capacitance of 29.4 pF/ft (Nom. Cap.). The nominal diameter of the conductor is 0.037 inches, and the overall cable diameter measures 0.1700 inches. The cable features an overall braid shield made of silver-coated copper, providing excellent electromagnetic shielding properties. With a nominal impedance of 50 ohms (Nom. Imp.), RG 303 U is suitable for various high-frequency applications where reliable signal transmission is crucial.
