TNC
TNC

Developed in the late 1950's, the TNC stands for Threaded Neill Concelman and is named after Amphenol engineer Carl Concelman. Designed as a threaded version of the BNC, the TNC series features screw threads for mating.

 

TNC are miniature, threaded weatherproof units with a constant impedance of 50 Ohms and operate at DC to 11 GHz. As a ruggedized version of the BNC, the TNC features a threaded coupling that offers extra mating stability. TNC connectors are used in many applications including Mil-Aero, instrumentation, and cable assemblies.

 

 

  • Threaded coupling interface ensures connector will not de-couple in vibration-intensive applications
  • Many TNCs are recognized under the component program of Underwriter's Laboratories and have undergone stringent testing from an independent laboratory
  • Frequency range DC to 11 GHz
