What are the key features of SFM-118-L2-LM-D-K-TR?
- 36-position dual-row socket at 0.050" pitch achieves high signal density in a small PCB footprint for compact embedded board designs
- Low-profile mating (LM suffix) reduces stacking height and overall assembly profile for space-constrained mezzanine applications
- Gold-plated contact finish ensures low contact resistance and reliable electrical performance across high mating-cycle lifetimes
- Tape-and-reel (TR) packaging enables seamless automated pick-and-place assembly on high-volume SMT production lines
What is SFM-118-L2-LM-D-K-TR used for?
The SFM-118-L2-LM-D-K-TR is designed for low-profile board stacking in embedded computing modules, FPGA mezzanine cards, and medical device PCBs where a 36-position 0.050" pitch socket with reduced stack height is required. Its gold-plated contacts maintain signal integrity in high-frequency digital and mixed-signal designs over repeated mating cycles. The surface-mount construction and tape-and-reel packaging make it well suited to automated assembly in compact, high-reliability electronic systems.

Frequently Asked Questions
How many signal positions does the SFM-118-L2-LM-D-K-TR provide, and what pitch are its contacts?
The SFM-118-L2-LM-D-K-TR provides 36 positions arranged in a dual-row layout at 0.050" (1.27 mm) pitch, with 18 contacts per row. The fine 0.050" pitch allows 36 signals to be routed within roughly half the board area of an equivalent 0.100" pitch connector, supporting density-optimized designs in compact system-on-module and mezzanine card applications.
How does the low-profile mating (LM) option affect overall PCB stack height compared to standard SFM variants?
The low-profile mating (LM) suffix reduces the connector's above-board height, lowering the total board-to-board stacking distance compared to standard SFM mating heights. This allows the two mated PCBs to be positioned closer together—often in the range of 1 mm to 3 mm separation—which is essential in thin embedded modules, wearable devices, and medical electronics requiring sub-10 mm overall assembly thickness.
When is the SFM-118-L2-LM-D-K-TR preferred over a 36-pin 0.100" pitch socket for FPGA daughter card designs?
The SFM-118-L2-LM-D-K-TR at 0.050" pitch is preferred when the FPGA daughtercard PCB area is constrained to less than half the footprint available for a 0.100" pitch alternative, or when the board stack height must be minimized. The low-profile mating variant specifically benefits thin form-factor designs such as SMARC or COM Express modules where connector height directly limits the system's ability to fit within an enclosure of 10 mm or less.
