What are the key features of SFM-141-L2-S-D-LC?

  • 82-position dual-row 1.27 mm pitch SMT socket for high-density signal interconnection
  • High-reliability socket design rated for hundreds of mating cycles in demanding environments
  • Gold-plated contacts ensuring low contact resistance and corrosion resistance over product lifetime
  • Surface mount footprint compatible with standard reflow soldering and pick-and-place assembly
  • Low-profile dual-row layout reducing board height compared to equivalent through-hole sockets

What is SFM-141-L2-S-D-LC used for?

The SFM-141-L2-S-D-LC is used in high-reliability mezzanine and daughter-card assemblies in aerospace, defense, and industrial computing where 82 signal lines must be routed across board interfaces with 1.27 mm pitch. It suits FPGA development boards, DSP modules, and ruggedized data acquisition systems requiring repeated board swapping during testing and maintenance. The surface mount design integrates into automated PCB assembly processes for high-volume production of embedded computing platforms.

Frequently Asked Questions

How many positions and what pitch does the SFM-141-L2-S-D-LC provide for board interconnection?

The SFM-141-L2-S-D-LC offers 82 positions in a dual-row configuration with 1.27 mm (0.050 inch) pitch, providing 41 contacts per row. This fine pitch enables routing of 82 signal or power lines across a mezzanine interface in a board footprint under 55 mm long, making it suitable for compact embedded modules.

For what kind of high-reliability applications is the SFM-141-L2-S-D-LC designed?

The SFM-141-L2-S-D-LC targets aerospace, defense, and industrial applications where connectors must withstand hundreds of mating and unmating cycles without degrading contact resistance below 30 mΩ. Its gold-plated contacts and high-reliability socket construction make it appropriate for ruggedized data acquisition cards, military communication modules, and avionics backplane interfaces subject to vibration and thermal cycling.

When is the 1.27 mm pitch of SFM-141-L2-S-D-LC preferable to the standard 2.54 mm pitch connector?

Choosing the 1.27 mm pitch of the SFM-141-L2-S-D-LC over a 2.54 mm pitch alternative cuts the connector footprint length by approximately 50% for the same 82-position count, critical when PCB length is constrained to under 60 mm. This finer pitch also reduces parasitic inductance per contact at high signal frequencies above 500 MHz, benefiting high-speed serial interface designs.

How does the surface mount design of SFM-141-L2-S-D-LC simplify manufacturing compared to through-hole socket alternatives?

The SMT design of the SFM-141-L2-S-D-LC eliminates the need to drill 82 through-holes per side into the PCB, reducing fabrication cost and allowing the connector to be placed on a 4-layer board without sacrificing inner-layer routing channels. It is compatible with standard lead-free reflow profiles peaking at 260°C, enabling single-pass assembly alongside other SMT components on the same board.
