The 245103-05-18.00 is a 75 OHM BNC straight plug to Mini SMB right-angle plug RF cable assembly utilizing RG 179 cable. The assembly features a BNC straight plug with brass construction and nickel plating, connected to a 75 OHM Mini SMB right-angle plug with brass construction and gold plating. The cable length is 18.00 inches (0.457 meters) with a tolerance of ±0.25 inches (±0.006 meters), and the assembly maintains 50 OHM impedance throughout. Design requirements include continuity verification and high-potential testing at 500 VRMS. This cable assembly is commonly used in RF and microwave applications requiring reliable impedance-matched connections between BNC and Mini SMB connectors.
