Lbs Coupling nut retention force > 450 N / 101,2 lbs Contact captivation > 27 N / 6,1 lbs Electrical data Requirements Impedance 50 Ω Frequency range DC… 11 GHz Dielectric withstanding voltage (at sea level) 1,5kV rms, 50 Hz (depending on cable) Working voltage (at sea level) unmated 500 V rms, 50 Hz (depending on cable) insulation resistance > 5.103 M Ω Contact resistance Center contact < 1,5 mΩ Outer contact < 1mΩ RF-leakage (between 2 and 3 GHz) > 60 dB he TNC connector was designed as a threaded version of the BNC to improve RF performance stability at higher frequencies fromDC up to 11 GHz. The threaded couplingmechanism improves control over the interface dimensions and allows them to be used under a higher environmental load than BNC, especially under a high vibration load. It is standardized according to IEC 60169-17.
