U.FL-R-SMT(01) — Ultra-Miniature Coax Receptacle for Internal RF Links
The gold-plated center contact handles the repeated mates within that cycle budget without degrading the signal path. Surface-mount termination with a solder shield tab — the board layout needs a ground plane cutout under the pad to maintain the 50 Ohm characteristic impedance through the launch. The beige LCP housing withstands reflow temperatures without wicking.
50 Ohm at 6 GHz — What the Frequency Rating Means for the RF Path
The 6 GHz maximum frequency covers 2.4 and 5 GHz Wi-Fi bands, Bluetooth, and most cellular LTE/5G sub-6 GHz bands with margin.
Operating Range and Material Choices
The -40°C to 90°C operating temperature covers most indoor consumer electronics, automotive cabin modules, and industrial control enclosures. It won't handle engine-bay heat or a soldering iron left on the pad too long — the LCP dielectric handles reflow but the 90°C upper limit is the mated operating ceiling. The gold-on-brass contact gives low and stable contact resistance across the 30-cycle life. The silver body finish is standard for U.FL — it's not a high-corrosion environment finish, so keep it out of condensing humidity or salt spray without conformal coating.
