MCX F Solder PCB Mount with Stand-off

Description

The MCX (Micro Coaxial) Female PCB Mount connector is an ultra-miniature RF interface designed for 50 Ohm systems where vertical space and signal precision are critical. This variant is specifically designed for through-hole soldering and features integrated stand-offs (bosses) on the base of the connector body. These stand-offs serve two primary functions: they provide a consistent gap for thorough cleaning of solder flux and they ensure the connector sits perfectly level on the PCB surface for superior mechanical alignment.

The connector features a Gold-Plated Brass body and a high-retention center contact to ensure maximum electrical conductivity and a low-resistance signal path. The snap-on coupling mechanism allows for quick, tool-less mating with MCX male plugs and supports 360-degree rotation, which reduces mechanical stress on the PCB solder joints during cable routing. Optimized for performance from DC to 6GHz, this connector is a “workhorse” for modern wireless infrastructure, providing a reliable bridge between internal PCB traces and external antenna systems or test points.

Key Technical Advantages

• Integrated PCB Stand-offs: The built-in bosses ensure the connector body is elevated slightly above the board, allowing for better solder wetting, easier post-solder inspection, and effective flux removal.

• Ultra-Miniature Footprint: The compact MCX design allows for high-density placement on congested circuit boards where standard SMB or SMA connectors would occupy too much real estate.

• Snap-On Convenience: The tool-less mating interface facilitates rapid assembly and maintenance in high-volume production environments.

• Gold-Plated Precision: Heavy gold plating on the body and contact surfaces ensures a high number of mating cycles and provides exceptional resistance to oxidation.

• Robust Through-Hole Mounting: The four-leg (quad-leg) mounting configuration provides superior structural integrity and pull-strength compared to surface-mount alternatives.
