TNC Type RF Connectors

Please note that you only need to register as a member for the first time.

TNC type rf connectors have an impedance of 50Ω and are used for power transmission in radio equipment, etc. They are equivalent in size to BNC type rf connectors, and many of the products in our lineup have couplings that replace the BNC plug mating part. The threaded coupling method makes these connectors highly durable against shock and vibration.

Some TNC type RF connectors are available for purchase from Digi-Key.

No cables with TNC connectors are available in stock.

Trivia: About Cables

JIS Standard
Japanese Industrial Standards (JIS) compliant cables. The higher the number of the part number, the thicker the cable. "D: 50Ω" and "C: 75Ω" represent the impedance.
MIL Standard
Compliant with US military standards for cables. Begins with the initials "RG" and is also called Mil-Spec.
Micro Coaxial Cables
Micro coaxial cables for attaching to miniature RF connectors such as U.FL.

Connector with excellent durability against shock, vibration, etc., due to the threaded coupling method.

TNC connectors have an impedance of 50Ω and are mainly used for power transmission in radio equipment, etc. When a 75Ω cable is used with a 50Ω type connector, it can be used with a 75Ω transmission line if the frequency is 200MHz or lower.


Communication equipment (terminals, mobile devices), measuring equipment, etc.
