SMP-MSLD-PCE-3: 18 GHz SMP Jack for Board-Edge RF
It uses a limited-detent snap-on fastening — the mating force is defined but not a full-lock, which means it can be quickly mated and unmated by hand without a tool, while still holding against moderate vibration.
Mounting and PCB Fit — Board-Edge Cutout with SMT
This connector mounts into a board-edge cutout with surface-mount shield and contact terminations. The board-edge cutout provides mechanical alignment and takes shear off the SMT solder joints, while the SMT pads handle the RF ground and signal connection. The dielectric is PTFE, which maintains a stable 50 Ohm impedance across the temperature range.
Comparing SMP-MSLD-PCE-3 with SMP-MSLD-PCE-5T
The SMP-MSLD-PCE-5T is the closest functional peer in the SMP-MSLD family — same SMP interface, same 50 Ohm impedance, same 500-cycle durability, same limited-detent snap-on. The key difference is frequency: the PCE-3 is rated to 18 GHz, while the PCE-5T extends to 26.5 GHz. If your RF chain operates above 18 GHz, the PCE-5T is the correct choice; for bands up to 18 GHz (Ku-band and below), the PCE-3 covers the same ground at a lower spec threshold. Both use beryllium copper contacts and gold body finish, so the mechanical and environmental performance is identical.
