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,studio equipment, satellite uplink/downlink stations,cable TV distribution and headend systems 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.

What is the difference between RF connectors and coaxial connectors?
They are often used interchangeably. However: Coaxial connector refers to the physical design (shielded cylindrical form). RF connector emphasizes its use in radio-frequency applications. Most RF connectors are coaxial.
What is “reverse polarity” (RP-SMA, RP-TNC)?
Reverse polarity means the gender of the center pin is swapped while keeping the outer body style unchanged. It was introduced to comply with regulatory requirements in Wi-Fi devices and to prevent connection with standard SMA/TNC.
What’s the lifespan of an RF connector?
Connector durability is rated in mating cycles: General-purpose connectors (BNC, SMA): 500 cycles. Precision connectors (2.92 mm, 2.4 mm): 500 cycles or less. Rugged telecom connectors (N, 7/16 DIN): 500 cycles.
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.
