The threaded fastening is on the connector body itself, so the mating SMA plug tightens directly against the jack's face, not through a panel. If your enclosure requires the connector to pass through a panel wall, the 0732511291 is the correct pick; for a PCB-edge launch, this 0732511142 is the one. The 50 Ohm impedance and 18 GHz maximum frequency are the two numbers that define the signal envelope. At 18 GHz, the VSWR and insertion loss are governed by the PTFE dielectric and the precision of the centre contact geometry — the polytetrafluoroethylene (PTFE) insulator keeps the dielectric constant stable across temperature, so the impedance holds from DC through the full band.","metaTitle":"Molex 0732511142 SMA Jack, 50 Ohm, 18 GHz, Board-Edge SMT","metaDescription":"Molex 0732511142 SMA jack, 50 Ohm impedance, 18 GHz max frequency, board-edge SMT mount, gold body.
