The Molex 0734120110 is a U.FL (UMCC) receptacle, male pin, from the 73412 series — a compact coaxial interconnect designed for internal RF signal routing in space-constrained devices. The snap-on fastening allows quick mating without tools, and the 30 mating cycle rating reflects the limited-mate design intent typical of U.FL connectors — it's built for a few assembly/disassembly cycles in production or field service, not daily reconnection.
Surface mount termination with solder shield termination means this part feeds through a standard reflow line — pick-and-place compatible, no hand-solder step. The Tape & Reel packaging (Cut Tape also available) keeps the line running without a tray changeover. Center contact is gold-plated brass over a phosphor bronze body with nickel finish; the dielectric is liquid crystal polymer (LCP), which holds dimensional stability through reflow.
