000-35650-75 is a BNC connector cap with chain and integrated 75 O resistor termination, designed for RF cable protection and impedance matching in 75 O systems. The connector features a nickel-plated brass body with gold-plated contacts, providing excellent corrosion resistance and reliable electrical performance. It is rated for industrial-grade applications and is compatible with standard BNC connectors operating from DC to 4 GHz (usable to 6 GHz for performance-grade applications). The 75 O impedance design allows customers to match system requirements in video, broadcast, and telecommunications applications. This termination cap is ideal for protecting unused BNC ports, preventing signal reflections, and maintaining system impedance integrity in cable assemblies, broadcast equipment, and instrumentation systems.
