TNC connectors

What are TNC connectors?

TNC connectors, also known as TNC coaxial connectors, RF TNC connectors or TNC threaded connectors, are professional interfaces designed to ensure stable and reliable connections in RF and microwave applications. Derived from the BNC family but using a threaded coupling, TNC connectors offer better high-frequency performance and improved mechanical stability.

Main characteristics of TNC connectors

TNC RF connectors are widely used when high electrical stability and secure coupling are required. Their key features include:

• Threaded coupling for a more secure connection compared to BNC, suitable for industrial and outdoor environments.
• Operating frequency up to 11 GHz, with certain versions optimized for microwave applications.
• Excellent electrical stability and low VSWR even in demanding conditions.
• High mechanical strength for applications subject to vibration or repeated handling.
• Multiple configurations including TNC male / TNC female, crimp, clamp, solder and panel-mount TNC connectors.

Where TNC connectors are used

TNC-type RF connectors are employed across many professional applications that require reliability and stable RF performance:

• Telecommunications – radio links, wireless networks, outdoor RF systems and antennas.
• RF and microwave systems – modules, amplifiers, filters, antennas and high-frequency equipment.
• Laboratory instrumentation – analyzers, RF generators, measurement systems and test setups.
• Industrial applications – RF sensors, automation systems and custom equipment.
• Aerospace and defense – whenever secure and stable threaded connections are required.

Available variants
