RG 403 — Coaxial Cable

RG 403 is a precision coaxial cable engineered for high-frequency and low-loss signal transmission. It features a silver-coated copper conductor with 7 strands of 0.004" wire, providing excellent conductivity and durability. The cable uses a PTFE (Polytetrafluoroethylene) dielectric with a diameter of 0.012", delivering low capacitance of 29.4 pF/ft and maintaining signal integrity over long distances. An overall silver-coated copper braid shield ensures superior protection against electromagnetic interference (EMI). The rugged Fluorinated Ethylene Propylene (FEP) jacket offers excellent resistance to heat, chemicals, and harsh environments, with an operating temperature range from -55C to 200C. With a nominal impedance of 50 ohms, a voltage rating of 1000V, and a compact 0.116" outer diameter, RG 403 is ideal for RF, microwave, aerospace, and instrumentation applications that demand high performance and reliability.
