245101-04-48.00 is a coaxial cable assembly that connects an SMA straight plug to a BNC straight plug using RG 58/U coaxial cable. The assembly is 48.00 inches (1.219 meters) in length and features a 50 ohm impedance characteristic, meeting MIL-STD-348 interface standards for both connector types. The cable includes heat shrink tubing for strain relief and protection. This assembly is designed for RF and microwave applications requiring reliable signal transmission across frequencies from DC to 1 GHz, with a high-voltage rating of 500 VRMS. It is commonly used in test equipment, instrumentation, and communication systems where precise impedance matching and signal integrity are essential.
