50 Ohm SMP Jack, 12 GHz — Right-Angle Through-Hole
The SMP-MSLD-PCT-6: It belongs to the SMP-MSLD series of blind-mate RF connectors, distinguished by the Limited Detent feature — a lower retention force than full detent that makes it easier to engage and disengage in dense board arrays or panel-mount stacks. Gold body finish and gold centre contact plating keep corrosion off the RF path across the rated 500 mating cycles.
What the 12 GHz Bandwidth Means on the Bench
The 12 GHz max frequency places this SMP jack in the moderate-bandwidth tier of the SMP-MSLD family. Siblings like the SMP-MSLD-PCS18T and SMP-MSLD-PCE-5T carry a 26.5 GHz rating, and the SMP-MSLD-PCT15T is rated to 18 GHz. The 12 GHz cap is not a defect — it reflects the dielectric material choice. This part uses a PTFE dielectric; the higher-frequency siblings use a Liquid Crystal Polymer (LCP) dielectric. For systems operating up to 12 GHz — common in microwave backhaul, satellite IF chains, and instrumentation — the PTFE dielectric gives stable phase performance with a proven material. If the design calls for operation above 12 GHz, one of the LCP-dielectric siblings is the correct pick.
Thermal Range and Materials
The PTFE dielectric holds its dielectric constant across that span, and the beryllium copper centre contact maintains spring force at both extremes. The brass body with gold finish resists oxidation in humid or salt-spray environments. The snap-on fastening type with Limited Detent means the connector pushes on and pulls off without tools — useful for rack-and-panel or blind-mate applications where the mating half is not easily reached.
