415-0029-018 is a fixed-length cable assembly featuring RG-316 coaxial cable terminated with SMA straight plug connectors on both ends. The assembly is 18 inches in length and utilizes connector model 142-0403-011 at both ends. The RG-316 cable with SMA connectors provides a 50-ohm impedance characteristic suitable for RF and microwave applications up to 12.4 GHz. The assembly is rated for a dielectric withstanding voltage of 750 Vrms and a working voltage of 250 Vrms, making it suitable for moderate-power RF signal transmission. This cable assembly is commonly used in test equipment, instrumentation, and communication systems where reliable RF connectivity and compact form factor are required.
