Description
The TNC (Threaded Neill-Concelman) series is a high-reliability RF interface designed to maintain electrical continuity in high-vibration environments where standard BNC connectors may fail. This female (jack) variant is specialized for the 3.58mm (0.141″) semi-rigid cable class, including RG402. Because semi-rigid cables utilize a solid copper outer conductor, this connector employs a direct-solder termination method, creating a seamless, airtight mechanical and electrical bond that is far superior to standard crimp designs in microwave applications.
By eliminating the crimp ferrule, this solder-on jack provides maximum EMI shielding and minimizes signal leakage. The design ensures a phase-stable connection, making it essential for precision instrumentation, satellite communication systems, and cellular base stations where signal purity and low VSWR are critical. Manufactured with a heavy-duty nickel or silver-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and reliable operation up to 11 GHz and beyond.
Key Technical Advantages
-
Optimized for RG402/0.141″: Precision-machined bore diameter designed specifically for the solid outer jacket of semi-rigid cables, ensuring a perfect fit and easier soldering process.
-
Direct-Solder Integrity: The solder-on body design creates a permanent, 360-degree electrical path that significantly reduces insertion loss and VSWR compared to mechanical terminations.
-
Vibration-Proof Threaded Interface: The 7/16-28 external threads provide a secure mechanical lock when mated, preventing signal intermittent issues in high-G aerospace or industrial applications.
-
Superior EMI/RFI Shielding: The solid-to-solid solder connection provides a highly shielded transition, critical for sensitive microwave circuits and high-frequency data transmission.
-
High-Frequency Performance: Engineered to support frequencies up to 11 GHz with exceptional stability, making it suitable for modern high-bandwidth wireless infrastructure.
