UFL F PCB MOUNT

Description

The U.FL series (compatible with I-PEX MHF and AMC interfaces) is one of the smallest RF connector series in the world, designed to meet the rigorous space constraints of modern portable electronics. This female (jack/receptacle) variant is designed for Surface Mount Technology (SMT), allowing it to be soldered directly onto the PCB via automated pick-and-place machinery. Its ultra-compact footprint and minimal vertical profile make it indispensable for engineers designing high-density circuit boards where every millimeter of space is critical.

Despite its subminiature size, the U.FL receptacle maintains a consistent 50-Ohm impedance and delivers exceptional performance up to 6 GHz. The connector features a snap-on coupling mechanism that provides a tactile “click” when mated, ensuring a secure electrical connection. Manufactured with gold-plated contacts and a high-temperature liquid crystal polymer (LCP) dielectric, it is built to withstand the high temperatures of lead-free reflow soldering while maintaining superior signal integrity for sensitive microwave frequencies.

Key Technical Advantages

• Ultra-Low Profile: Offers a mated height of 1.9mm to 2.5mm (depending on the mated plug), making it ideal for the thinnest smartphones, wearables, and tablet devices.

• Exceptional Space Efficiency: Occupies a tiny PCB footprint (approx. 3mm x 3mm), allowing for maximum component density in compact wireless modules.

• Broadband Microwave Performance: Optimized for 50-Ohm systems from DC to 6 GHz, covering all major Wi-Fi 6E, Bluetooth, and sub-6 GHz 5G frequency bands.

• Automated Assembly Ready: Supplied in tape-and-reel packaging for high-speed automated SMT placement, reducing manufacturing costs and increasing consistency.

• High-Reliability Contact: Gold plating ensures low contact resistance and stable performance even in high-vibration environments like automotive or industrial IoT.
