SMC F CRIMP for LMR100/RG174/RG316 Cable

Description

The SMC Female (Jack) Crimp Connector is a subminiature threaded RF interface designed for environments where mechanical stability and signal integrity are critical. While similar in size to the SMB series, the SMC utilizes a #10-32 threaded coupling instead of a snap-on mechanism. This threaded interface ensures a secure, semi-permanent connection that is highly resistant to vibration, making it a preferred choice for onboard avionics, mobile telecommunications equipment, and ruggedized industrial sensors.

This variant is specifically optimized for high-performance micro-diameter 50-Ohm cables, including LMR100, RG174, and RG316. It features a dual-crimp termination system for both the center conductor and the outer ferrule, providing an industrial-strength mechanical bond and excellent electrical continuity. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, the connector maintains a low VSWR (Voltage Standing Wave Ratio) from DC up to 10 GHz. Its robust construction ensures reliable performance even in harsh environments subject to extreme temperature fluctuations and mechanical shock.

Key Technical Advantages

• High-Vibration Threaded Security: The #10-32 threaded interface prevents accidental disconnection and maintains constant contact pressure, outperforming snap-on connectors in high-motion environments.

• Universal Micro-Cable Compatibility: Precision-calibrated for the standard dimensions of LMR100, RG174, and RG316 (approx. 2.5mm–2.8mm OD), ensuring a secure mechanical grip and optimized electrical path.

• Extended Frequency Performance: Engineered to support stable signal transmission up to 10 GHz, making it suitable for high-frequency microwave and wireless broadband applications.

• High-Strength Crimp Termination: The dual-crimp design provides exceptional pull-off resistance and superior EMI/RFI shielding effectiveness.

• Superior Corrosion Resistance: Premium gold-over-nickel plating on all critical surfaces ensures low contact resistance and prevents oxidation over long-term deployments.

Key Features

• Interface Type: SMC Female (Jack) with 50-Ohm threaded coupling.

• Cable Compatibility: Optimized for LMR100, RG174, and RG316 coaxial cables.

• Termination Method: High-reliability crimp for both the center pin and the outer ferrule.

• Premium Materials: Features a gold-plated brass body and a high-performance PTFE dielectric for thermal and electrical stability.

• Compact Footprint: Ideal for high-density internal equipment wiring where threaded security is required in a subminiature form factor.
