It is a single-port, 50 Ohm connector rated to 6 GHz, designed for board-level RF interconnects where a compact, snap-on mating interface is needed — typically inside wireless modules, GPS receivers, or IoT transceivers where the antenna signal path runs through a short coaxial jumper to the PCB. The snap-on fastening means it locks with a push, no threading — fast assembly, but the 30 mating cycles tell you this is a set-and-forget interconnect, not a test-point or a repeatedly serviced harness. ## Why the 30 Mating Cycles Matter Thirty mating cycles is a low figure — a typical SMA or MMCX jack will handle 500 or more. That rating reflects the U.FL miniaturisation: the tiny spring-finger contact wipes a thin gold surface, and after a few dozen mates the plating wears enough to shift contact resistance. For the field-service technician this means: if you are swapping a radio module that uses this jack, plan to replace the connector on the board after a few service cycles, not re-use it indefinitely. ## Lifecycle Reality — This Part Is Obsolete The A-1JB-100 carries an Obsolete status from the manufacturer. No stock is held; no lead-time number is published. This jack mates with any standard U.FL (UMCC) plug that has a snap-on latch and a female centre socket — the interface is defined by the industry U.FL form factor. The housing is white LCP, which withstands lead-free reflow temperatures without warping.","metaTitle":"A-1JB-100 U.FL/AMC Jack, 50 Ohm, 6 GHz, SMT, Obsolete","metaDescription":"A-1JB-100 U.FL (UMCC)/AMC jack, 50 Ohm, 6 GHz max, SMT, gold-plated centre pin.
