SMP interface, 50 Ohm, 18 GHz — what this connector does
The SMP-MSLD-PCS-T: That frequency ceiling puts it at the top end of the SMP class — most SMP connectors top out around 12 GHz without a bullet adapter. The snap-on fastening gives a quick blind-mate connection for board-to-board or module-to-cable RF links, with 500 mating cycles before the retention starts to fade. Gold centre contact and gold body finish keep the signal path corrosion-free through repeated connects.
SMT assembly with pick-and-place cap
The pick-and-place cap and solder retention features mean this connector was designed for automated reflow assembly, not hand-soldering. The LCP dielectric handles the 260°C peak reflow profile without warping the centre contact alignment — important because a 0.1 mm shift in the pin position changes the impedance match above 10 GHz. Supplied on Tape & Reel or Cut Tape, so it feeds straight into a standard pick-and-place feeder.
That means the manufacturer will continue to support existing production runs, but no new sockets or design wins should be built around this part number. If you are maintaining a fielded board, this connector is still available to order. For a new layout, look at the SMP-MSLD series for an active alternative with the same footprint and RF performance.
Temperature range and deployment context
That makes this jack a candidate for engine-compartment-mounted RF modules, satellite payloads, or outdoor radio heads where the enclosure sees direct solar gain. The gold body and LCP dielectric don't degrade or outgas at the high end, so the 50 Ohm impedance and 18 GHz bandwidth hold across the full temperature swing.
