TNC F Darlin Panel Mount Solder

Description

The TNC (Threaded Neill-Concelman) series is a high-reliability RF interface designed to maintain constant electrical continuity in environments subject to vibration and mechanical stress. This D-Hole Panel Mount variant (commonly known as a bulkhead “D-Flat” mount) is designed for rigid integration into equipment panels. The “D” shape of the threaded body fits into a corresponding flat-sided panel cutout, which physically prevents the connector from spinning when the external TNC male plug is tightened or loosened, ensuring a permanent and secure grounding path.

Unlike crimp-style connectors, this variant features a solder-cup or solder-post termination, allowing for direct attachment of internal chassis wiring or the center conductor of a coaxial cable. This makes it a versatile solution for prototyping, laboratory equipment, and industrial RF modules where internal space is tight or specialized crimping tools are not practical. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and low VSWR up to 11 GHz.

Key Technical Advantages

• Anti-Rotation D-Flat Profile: The precision-machined “D” flat ensures the connector remains fixed during installation and mating cycles, protecting internal solder joints from torsional stress.

• Direct Solder Termination: Features a high-conductivity solder cup for easy and reliable internal wiring, ideal for custom chassis builds and specialized RF instrumentation.

• Vibration-Proof Threaded Interface: The 7/16-28 external threads provide a secure mechanical lock, preventing signal intermittent issues common in industrial and mobile applications.

• Compact Bulkhead Mounting: Includes a heavy-duty mounting nut and lock washer, enabling a clean and flush professional appearance on panels while maintaining high EMI shielding.

• Superior Environmental Build: The nickel-plated brass construction and PTFE dielectric offer excellent resistance to thermal cycling and oxidation, ensuring long-term signal stability.
