The TNC series includes coaxial connectors that are very commonly used and are used up to a frequency of 11 GHz. They are similar in size to the BNC series but have a threaded coupling. Versions with 50 ohm and 75 ohm surge impedance are available. Connector variants are available for flexible, semi-flexible and semi-rigid cables. The TNC series PCB connectors are available in solder and press-fit versions. Depending on the version, cables are connected by crimping, clamping or soldering. The vibration-resistant TNC series of connectors are used in signal, data and video transmission. TNC connectors are cost-effective alternatives for coaxial connections at high frequencies.
