U.FL-R-SMT-1(80)

U.FL-R-SMT-1(80) is the surface-mount receptacle of Hirose's U.FL ultra-small coaxial series — 50 Ω characteristic impedance, and Hirose's current product page rates the frequency range to 8 GHz (older series catalogues printed 6 GHz; the current page governs). Hirose's specifications: one position, vertical SMT, gold plating on the centre contact and silver on the outer contact, 30 mating cycles, operating range −40 °C to +105 °C, body 3.0 x 3.1 x 1.25 mm, 0.016 g. The (80) suffix is the packing code, and it is part of the orderable part number: it denotes the 10,000-piece tape-and-reel form — the same receptacle body exists as (01) in 100-piece bags and (60) on 4,000-piece reels. Hirose code CL0331-0472-2-80. The selection point is the antenna and RF-module connection standard for compact wireless devices. Selection advice: U.FL is a limited-cycle connector — 30 matings is the rating, so treat it as a factory and service connection, not a user port, and always order by the full code including the packing suffix.
