The 245101-01-18.00 is a coaxial cable assembly featuring an SMA crimp plug connector on one end and a BNC crimp plug connector on the other end, utilizing RG-316/U coaxial cable as the transmission medium. The assembly is designed with a nominal impedance of 50 ohms and operates across a frequency range of DC to 3.0 GHz, meeting stringent electrical performance requirements including continuity and high-voltage withstand capability of 500 VRMS. The cable length is specified at 18.00 inches (0.457 meters) with a tolerance of ±0.25 inches, and includes heat shrink tubing for strain relief and environmental protection. This cable assembly is commonly used in RF and microwave applications, test equipment, and communication systems where reliable signal transmission and connector compatibility between SMA and BNC interfaces are required.
