It's a free-hanging, in-line connector with a snap-on fastening — the kind you push on until it clicks, no threads, no torque wrench. Rated for 50 Ohm impedance and 3 GHz maximum frequency, it's built for internal RF interconnects where board space is tight and the signal path needs a controlled impedance through a small coaxial cable. The kit includes the connector body and a heat shrink tube (2 pcs total) for strain relief and environmental sealing at the cable-to-connector junction. This plug is designed for cable group 1.5D-2W, 1.5D-HQEW, 1.5QEW — those are the thin coaxial cables typical of internal antenna feeds in portable electronics. The shield is terminated by crimp (the outer braid gets compressed into the body), and the center conductor is soldered to the contact. The included heat shrink goes over the crimp barrel to protect the braid from wicking and to add flex relief at the back of the connector. ## Mating and Mounting Reality Free-hanging means no panel cutout — the connector floats on the cable and mates to a board-mounted U.FL (UMCC) receptacle. The snap-on latch gives positive retention; you'll hear and feel the click when it's fully seated. The 1000-cycle rating means the gold-on-gold contact interface can handle repeated mate/unmate cycles without the center pin fretting or losing spring force — important for test points, programming headers, or modules that get swapped in the field.","metaTitle":"Hirose UM-QP-1.5WCR3A(40) U.FL Plug, 50 Ohm, 3 GHz","metaDescription":"Hirose UM series U.FL (UMCC) plug, female socket, 50 Ohm impedance, 3 GHz max, 1000 mating cycles.
