The white LCP housing and gold-plated brass center contact are standard for this ultra-miniature RF interface, typically used inside wireless modules, GPS receivers, and IoT radios where the board-to-cable connection needs to be compact and mated once during final assembly. The 50 Ohm nominal impedance and 6 GHz maximum frequency define the usable signal bandwidth — this jack supports common wireless bands (Wi-Fi, Bluetooth, cellular up to mid-band 5G) but rolls off before mmWave. The 30 mating cycles are typical for a U.FL-class interconnect; the snap-on latch is designed for a single mate during device assembly, not repeated field service. The SMT termination requires a reflow profile compatible with LCP (Liquid Crystal Polymer) — the housing withstands lead-free soldering temperatures without distortion. ## Compatibility and Mating Half This jack mates with any standard U.FL (UMCC) or AMC-series plug/cable assembly that uses the snap-on interface and a female center socket. The male pin on the A-1JB-250 is the board-mount side; the cable-end connector must have a female center contact. The 50 Ohm impedance is maintained across the mated pair when the cable assembly is also 50 Ohm.","metaTitle":"A-1JB-250 U.FL (AMC) Jack, 50 Ohm, 6 GHz, SMT, Obsolete","metaDescription":"A-1JB-250 U.FL (UMCC) AMC series jack, male pin, SMT, 50 Ohm, 6 GHz max, 500 V, 30 mating cycles.
