Key Features
- 72-position dual-row 0.050" pitch layout provides a high-density 36-per-row footprint for FPGA expansion and mezzanine board applications
- Keyed housing (K option) prevents incorrect connector mating, protecting 72-pin PCB designs from misalignment damage during board stack-up
- Gold-plated contacts rated at 1 A per pin with -55°C to +125°C operating temperature support reliable high-cycle use in industrial embedded systems
Applications
The SFM-136-L2-FM-D-A-K is designed for dense mezzanine board stacking in applications such as FPGA expansion boards, data acquisition modules, and industrial single-board computers where 72-pin high-reliability signal interconnects are required. Its keyed surface-mount design with gold contacts ensures consistent connectivity in automated assembly lines and field-deployed embedded computing systems operating across wide temperature ranges.

Frequently Asked Questions
How many positions does the SFM-136-L2-FM-D-A-K provide per row in its dual-row layout?
The SFM-136-L2-FM-D-A-K offers 72 total positions arranged in dual rows of 36 pins each at a 0.050" (1.27 mm) pitch, making it a high-density choice for FPGA mezzanine cards and industrial compute modules that require large signal bus widths in a compact connector footprint.
For a ruggedized embedded computing design, what temperature range does the SFM-136-L2-FM-D-A-K cover?
The SFM-136-L2-FM-D-A-K operates across -55°C to +125°C, with gold-plated contacts rated at 1 A per pin, making it appropriate for harsh industrial and military-grade embedded systems that must maintain reliable signal integrity across extreme thermal cycling conditions.
What does the 'FM' option in SFM-136-L2-FM-D-A-K signify compared to a standard SFM variant?
The 'FM' designator in the SFM-136-L2-FM-D-A-K indicates a specific lead style suited for flush-mount or co-planar surface-mount assembly, which affects the solder tail length and standoff height — typically 0.8 mm — influencing the mated stack height and the PCB layout footprint in mezzanine board designs.
