50 Ohm SMP Jack — 12 GHz, Limited Detent, SMT
The SMP-MSLD-PCR-T: It uses a limited-detent snap-on mating interface — the middle retention option in the SMP family, giving a positive hold without the high extraction force of a full-detent design.
Where This Sits in the SMP Series
The SMP-MSLD-PCR-T shares the SMP-MSLD base number with siblings like the SMP-MSLD-PCS18T, but the PCR-T suffix signals a 12 GHz frequency ceiling versus the 26.5 GHz of the PCS18T and PCE-5T. The difference is the dielectric — PEEK here versus PTFE in the higher-frequency variants. If your signal path stays under 12 GHz, the PCR-T saves cost; if you need the full SMP bandwidth to 26.5 GHz, step to the PCS18T or PCE-5T.
SMT Termination and Board Layout
Surface-mount termination with solder shield termination — the contact and outer shell both reflow in the same pass. The 50 Ohm impedance is set by the interface geometry, not the PCB launch, so the board trace needs a 50 Ohm controlled-impedance line to the pad.
Material and Environment
Limited detent means the snap-on ring gives a tactile click on mate but releases with moderate pull; it is not a full-detent lock, so it suits applications where the connector is periodically unmated.
