TNC RF Connectors Guide: Types, Structure, and Uses Explained
Summary
Tyclon's TNC RF connectors feature a standard 50 Ω impedance, optimized for reliable power transmission in radio and communication systems. Although similar in size to BNC connectors, the difference lies in the TNC's secure threaded coupling, which replaces the BNC bayonet style. This robust threaded mechanism ensures a stable connection, superior performance, and enhanced durability—vital in environments subject to shock and vibration.
TNC RF Connectors by Type
Micro-Coaxial Cables
Trivia: Compatible Cable Types
- MIL Standard Cables: These cables, also known as Mil-Spec, are engineered to meet rigorous US military specifications for performance and durability. They often feature the "RG" prefix, which stands for "Radio Guide," reflecting their roots in radio technology. They are critical in demanding applications like defense, aerospace, and telecommunications, where reliability is non-negotiable.
- Micro Coaxial Cables: These ultra-thin cables are designed to connect to miniature RF connectors like U.FL. They ensure signal integrity in space-constrained devices such as smartphones, laptops, and medical equipment, making them vital for modern compact electronics.
TNC RF Connector Features
Coupling Method
Threaded coupling ensures excellent durability against shock, vibration, and similar stresses.
Impedance
TNC connectors have a 50 Ω impedance, perfect for power transmission in radio equipment. They also work with a 75 Ω cable and transmission line at 200 MHz or lower frequencies.
TNC RF Connectors Applications
Our TNC RF connectors, are vital in communication equipment such as terminals and mobile devices, measuring instruments, and wireless networking systems. Crafted from brass or stainless steel with gold-plated contacts, they provide 50 Ω impedance and support frequencies up to 11 GHz. Their threaded coupling ensures secure, reliable connections, ideal for applications in harsh, vibrating environments.

TNC RF Connector FAQs
QWhy are there so many small lots of made-to-order products?
QWhy are there so many small lots of made-to-order products?
Many TNC plugs can be assembled by replacing the coupling with a BNC 50Ω plug. Since assembly can be done in about 1W after receiving an order, there are cases where a BNC50Ω plug can be assembled if available, even if it is not available in TNC's regular products.

QWhy is BNC stamped on TNC connectors?
QWhy is BNC stamped on TNC connectors?
Some TNC connectors are stamped with BNC because they are made from the same materials as BNC connectors.
QIs there a way to make the cable assembly more inexpensive?
QIs there a way to make the cable assembly more inexpensive?
We have connectors with a crimp-type cable attachment. Although a crimping tool is required for the assembly, it is lighter and less expensive than the clamping type connectors. You do not need to purchase crimping tools if you request us to process the cable assembly.
QWhat impedance options do Tyclon TNC connectors support?
QWhat impedance options do Tyclon TNC connectors support?
TNC connectors are primarily 50 Ω for RF and microwave applications, with 75 Ω versions available for video and broadcast uses. While 50 Ω connectors can work with 75 Ω cables up to 200 MHz with minimal loss, matching impedance is recommended for optimal signal integrity.
QWhat's the difference between standard and reverse polarity (RP-TNC) connectors?
QWhat's the difference between standard and reverse polarity (RP-TNC) connectors?
Standard TNC connectors have a female contact in the jack and a male contact in the plug. RP-TNC connectors reverse this (male in jack, female in plug) to prevent mating with standard connectors commonly used in Wi-Fi and wireless networking.
QWhat materials are used in Tyclon's TNC connectors?
QWhat materials are used in Tyclon's TNC connectors?
Tyclon uses brass or stainless steel for durability and corrosion resistance, gold-plated center contacts for conductivity, and PTFE (Teflon) dielectric for low signal loss. Some TNC connectors may be adapted from BNC materials, occasionally bearing a "BNC" stamp.
QWhat cable types are compatible with Tyclon TNC connectors?
QWhat cable types are compatible with Tyclon TNC connectors?
Our TNC connectors are compatible with MIL-Standard Coaxial Cables (RG-11/U, RG-142B/U, RG-55/U, RG-55A/U, RG-58/U, RG-58A/U, RG-59/U, RG-59A/U, RG-62/U, RG-62A/U, and RG-8/U) and Micro-Coaxial Cables (1 × 32 AWG (7/0.08) D = 1.32 mm).
QAre Tyclon TNC connectors compatible with SMA or N-type connectors?
QAre Tyclon TNC connectors compatible with SMA or N-type connectors?
Due to differing threads and sizes, TNC connectors aren't directly compatible with SMA or N-type connectors, but Tyclon offers adapters for seamless interconnectivity.
QHow do Tyclon TNC connectors perform in high-vibration environments?
QHow do Tyclon TNC connectors perform in high-vibration environments?
