UFL M PCB MOUNT

Description

The U.FL series (compatible with I-PEX MHF and AMC interfaces) is the industry standard for ultra-compact RF interconnects. This male (receptacle) variant is designed for Surface Mount Technology (SMT), providing a permanent board-side docking point for U.FL female cable assemblies. Engineered for the most space-constrained environments, this connector is a staple in the design of IoT devices, smartphones, and embedded wireless modules where traditional threaded connectors are too large.

Maintaining a strict 50-Ohm impedance, this connector delivers reliable microwave performance up to 6 GHz. The male receptacle features a center post and outer ground ring designed to provide a secure “snap” when mated with a female plug, ensuring mechanical stability and electrical continuity. Manufactured with gold-plated contacts and high-temperature resistant liquid crystal polymer (LCP), it is optimized for high-volume reflow soldering processes while ensuring minimal insertion loss and low return loss for sensitive 5G and Wi-Fi 6E signals.

Key Technical Advantages

• Extreme Miniature Footprint: Occupies minimal PCB real estate (typically 3mm x 3mm), allowing for maximum layout density in modern multi-layered circuit boards.

• Reflow Solder Compatible: Built with LCP dielectric materials that withstand the high temperatures of standard lead-free SMT reflow profiles without deformation.

• Standardized Compatibility: Fully intermateable with U.FL female cable plugs and equivalent interfaces like I-PEX MHF I, ensuring universal compatibility across wireless hardware.

• Tactile Mating Feedback: The snap-on interface provides clear mechanical feedback upon connection, ensuring a fully seated and secure RF path during assembly.

• Broadband Signal Integrity: Supports high-speed data transmission across a wide frequency spectrum (DC-6 GHz), making it ideal for the latest generation of wireless communication standards.
