Overview
The TNC (Threaded Neill Concelman) connector is a threaded version of the BNC, offering secure, vibration-resistant connections for RF and microwave applications. Its 7/16-28 threaded coupling provides reliable mating and stable performance, even in demanding environments. Standard TNC connectors operate up to 11 GHz, while precision types reach 18 GHz, with 50 ohm and 75 ohm variants available. Known for low signal loss and durability, TNC connectors are widely used in telecommunications, antennas, WLAN, test equipment,network analyzers, spectrum analyzers, and oscilloscopes,RF/microwave test benches and calibration equipment and military systems. Compact and rugged, the TNC connector delivers consistent electrical performance and is ideal for both indoor and outdoor applications.

FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material beryllium contacts offer better durability.
ROHS & REACH Compliance
Our products fully comply with ROHS & REACH regulations.

Other: Aluminum, titanium alloy
Can RF connectors be reused?
Yes, but performance degrades with wear. Precision connectors (used in test equipment) should be handled carefully—damage to threads or pins increases VSWR and insertion loss.
What’s the difference between threaded, bayonet, and push-on RF connectors?
Threaded (SMA, N, TNC): Secure, vibration-resistant. Bayonet (BNC): Quick connect/disconnect. Push-on (MCX, SMP): Ultra-fast, compact, used in high-density modules.
Are RF connectors interchangeable between brands?
Yes, if they follow the same standard (e.g., SMA-to-SMA). However, tolerances, plating, and dielectric quality vary — mixing low-quality and precision connectors can damage equipment.
How do environmental conditions affect RF connectors?
Temperature extremes can cause expansion/shrinkage and change performance. Humidity and salt spray may cause corrosion (use stainless steel or weatherproof designs). Vibration may loosen bayonet types — use threaded connectors in harsh environments.
