Series TNC RF Coaxial Connector, short for Threaded Neill-Concelman Connector, is a high-reliability RF connecting component featuring a precision threaded locking mechanism. As the threaded version of BNC connectors, it complies with MIL-C-39012, IEC 60169-17 and GJB681A standards, balancing excellent high-frequency performance, strong anti-vibration capability and wide compatibility, serving as a core interconnection part in harsh-environment RF systems.
The series boasts superior electrical performance with versatile specifications. It offers dual impedance options of 50Ω and 75Ω: 50Ω for RF communication, radar and test systems (supporting DC to 18GHz for high-end models), 75Ω for video and broadcast applications (DC to 1.5GHz). Key parameters are outstanding: VSWR ≤1.30 for straight types, contact resistance of inner conductor ≤2.0mΩ and outer conductor ≤0.2mΩ, insulation resistance ≥5000MΩ, ensuring stable, low-loss signal transmission.
Its unique advantage lies in the threaded coupling design, which provides firmer connection than bayonet-type BNC connectors, effectively resisting vibration and preventing accidental loosening—ideal for outdoor and mobile scenarios. Manufactured with precision processes, it adopts nickel-plated brass housing, gold-plated contacts and PTFE insulators, withstanding -65℃ to +165℃ working temperature, 500+ plugging cycles and harsh conditions like salt fog and thermal shock.
Widely applied in wireless base stations, antennas, radar systems, aerospace equipment, test instruments and outdoor communication devices, it is usually paired with RG-58, RG-316 coaxial cables. As a mature, high-reliability solution, it remains a mainstream choice for anti-vibration, high-frequency RF interconnection in complex industrial and aerospace scenarios.
