SMP Jack with Full Detent for High-Vibration RF Links
The Amphenol RF SMP-MSFD-PCT-2 is a 50 Ohm SMP jack, male pin, designed for board-mount RF interconnects where the connection must stay put under shock and vibration. The full detent feature gives it a positive snap-on lock that resists accidental unmating — a step up from standard SMP connectors that rely on a smooth bore with no retention. Rated DC to 12 GHz, it covers L-band through X-band and most Ku-band downlinks, making it a solid fit for compact radio modules, phased-array feeds, and test fixtures.
Through-Hole Mount and Solder Termination
This SMP jack mounts through a hole in the PCB and terminates with solder to the shield and center conductor. The shield termination is solder — not a press-fit or clamp — so the board footprint needs plated through-holes sized for the body diameter and center pin. The snap-on fastening type mates with any standard SMP plug or bullet that has the full detent groove; a smooth-bore SMP receptacle will not latch. For a blind-mate or push-on application without the retention requirement, a standard SMP jack (non-detent) is the alternative, but this part is the one to specify when the cable assembly runs through a vibrating chassis or a portable instrument.
The base product number is SMP-MSFD; the -PCT-2 suffix indicates the full detent variant with through-hole solder termination. No official replacement or cross-reference exists because the part is current-production. For volume pricing and lead time, submit an RFQ with your target quantity and delivery window.
