U.FL-R-SMT-1(60) — Hirose U.FL SMT Receptacle for 50 Ohm Coaxial Interconnects
The Hirose U.FL-R-SMT-1(60) is a surface-mount receptacle in the U.FL (UMCC) series, designed as the board-side half of a low-profile, 50 Ohm coaxial interconnect. It is a receptacle with a male pin centre contact, mating with the corresponding U.FL cable plug (female socket) for a snap-on connection. This is the part you specify when board real estate is tight and the RF path needs controlled impedance up to 6 GHz — think embedded antennas for Wi-Fi, Bluetooth, GPS modules, or any compact wireless design where a standard SMA or MMCX jack would be too tall or too wide. The centre contact is gold-plated brass, the body is silver-plated phosphor bronze, and the housing is beige liquid crystal polymer. The gold on the centre pin is what matters for signal integrity at this impedance — it resists oxidation over the 30 mating cycles the connector is rated for. That 30-cycle limit is the real constraint for field-service planning: this is a set-and-forget connector for the life of the product, not a daily-disconnect test port. The single-port, 1-circuit design is the standard U.FL footprint — no multi-position variants in this series.
What the 50 Ohm / 6 GHz Rating Means for Your RF Design
The 6 GHz maximum frequency means this connector supports the 2.4 GHz and 5 GHz Wi-Fi bands, Bluetooth, GPS /L5, and sub-6 GHz cellular bands, but it is not rated for mmWave applications above 6 GHz. The snap-on fastening is the U.FL trademark — it provides a positive tactile lock without the thread of an SMA or the push-pull of an MMCX, saving board height.
Mating and Compatibility — What It Works With
The snap-on interface is universal across the U.FL series.
