It belongs to the UM series, Hirose's micro-coaxial connector family that is mechanically compatible with the widely used U.FL interface standard. The connector is supplied in bulk and includes the receptacle body, a lockwasher, and a nut for front-side bulkhead mounting. The 50-Ohm impedance and 1 GHz maximum frequency rating suit this connector for lower-frequency RF applications such as GPS antennas, cellular modules, and wireless IoT devices where signal integrity up to 1 GHz is sufficient. The brass body with nickel finish and gold-plated center contact provide corrosion resistance and reliable signal transfer over 1000 mating cycles. ## Last Buy — Procurement Planning Required The UM-QR-1(41) carries a Last Buy lifecycle status, meaning Hirose has announced end-of-life for this part and final production orders are being accepted. Buyers should secure their lifetime buy quantities or identify a suitable replacement before stock is exhausted. No official successor order code is listed in the available documentation. Given the Last Buy status, early engagement with sourcing is recommended to avoid a last-minute scramble. The UM-QR-1(41) mates with any standard U.FL (UMCC) plug that uses a snap-on fastening mechanism. The male pin center contact requires a solder cup termination for the coaxial cable center conductor, while the shield is terminated via a solder tag on the connector body. The bulkhead front-side nut secures the connector to the panel with the included lockwasher. The gold-plated brass center contact and nickel-plated brass body ensure consistent contact resistance over the rated 1000 mating cycles.","metaTitle":"Hirose UM-QR-1(41) U.FL Receptacle, 50 Ohm, 1 GHz, Last Buy","metaDescription":"Hirose UM-QR-1(41) U.FL (UMCC) receptacle, male pin, 50 Ohm, 1 GHz max, 1000 mating cycles.
