Frequently Asked Questions
What is the total contact count and pitch of the SFM-149-L2-FM-D-LC?
The SFM-149-L2-FM-D-LC provides 98 contacts arranged in a dual-row configuration with 49 pins per row, at a pitch of 0.050" (1.27 mm). This makes it suitable for routing up to 98 signal or power lines in a compact SMT footprint.
Which PCB assembly methods are compatible with the SFM-149-L2-FM-D-LC connector?
This connector uses surface-mount termination, fully compatible with standard SMT reflow soldering processes at up to 260°C. The L2 lead style positions the mounting tails on the PCB surface, ensuring consistent solder joint formation and reliable mechanical retention during automated assembly.
What are the typical application areas for the 98-position SFM-149-L2-FM-D-LC in embedded systems?
The 98-position dual-row layout is ideal for FPGA daughtercard interfaces, high-speed data acquisition modules, and multi-channel communication boards that require dense parallel signal connectivity. Systems operating with 49 or more differential pairs, or up to 98 single-ended signals at 0.050" pitch, can leverage this connector in a minimal PCB footprint.
How does the SFM-149-L2-FM-D-LC compare to through-hole connectors of similar pin count for stack height?
The surface-mount design of the SFM-149-L2-FM-D-LC reduces PCB stack height by approximately 2 mm to 3 mm compared to through-hole connectors of comparable 98-pin counts, because there are no through-board pins. This makes it better suited for slim mezzanine assemblies with tight vertical clearance constraints.
