Product details

SMP Plug for RF Board-Edge Integration

The SMP-PL-P-HH-ST-EM3: This is the limited-detent variant, meaning the mating interface provides a controlled retention force suitable for moderate-vibration environments where the connector must still be field-releasable without tools.

Mounting and Termination for RF Layout

This plug is terminated by soldering the center contact and shield to the PCB at the board edge, using a cutout in the board to position the connector body. The surface-mount attachment suits automated assembly, but the tray packaging indicates this part is typically handled in lower volumes or for engineering builds rather than high-speed reel-fed lines.

Frequently asked questions

What is the impedance of SMP-PL-P-HH-ST-EM3?

The SMP-PL-P-HH-ST-EM3 is a 50 Ohm connector, which is the standard impedance for RF and microwave signal paths up to several tens of GHz.

Does SMP-PL-P-HH-ST-EM3 mate with standard SMP female connectors?

Yes, as an SMP plug with a male pin, it mates with standard SMP female receptacles (jack, female socket) that use the same snap-on fastening interface. The limited detent means the mating force and retention are moderate — ensure the female counterpart also specifies limited detent for consistent engagement force.
