TNC

Ideal for demanding, high-vibration and harsh environments, TNC miniature connectors perform at a constant 50 Ohm impedance and operate from DC to 11 GHz

NC miniature connectors are considered mid-sized and use a threaded coupling arrangement. The stability of the threaded coupling allows the connectors to perform up to 11 GHz with improved resistance to adverse environments including vibration, moisture, corrosion and thermal variations. IP68 bulkhead versions are available. Typical applications include mobile communications, avionics and antenna ports for wireless base units.
