Frequently Asked Questions
What contact finish does the SFM-109-T2-L-D use on its mating surface, and why does it matter?
The SFM-109-T2-L-D uses a gold contact finish on the mating surface over a nickel barrier, providing low contact resistance and excellent corrosion resistance. The termination side uses tin (Sn) with nickel (Ni) barrier, ensuring reliable solderability during reflow for all 18 positions.
How does the 0.050" pitch dual-row layout of SFM-109-T2-L-D benefit high-density board designs?
The 0.050" (1.27 mm) pitch dual-row female socket allows 18 positions in a body length of only 0.605", achieving high interconnect density per unit PCB area. This makes the SFM-109-T2-L-D ideal for compact embedded modules and mezzanine boards where space is constrained but signal count demands are high.
Which PCB connector applications commonly use the SFM-109-T2-L-D surface-mount socket?
The SFM-109-T2-L-D is commonly used in board-to-board mezzanine stacking, FPGA daughter cards, industrial control modules, and data acquisition systems. Its 18-position dual-row configuration and 0.050" pitch allow reliable high-density interconnects with gold-mated contacts rated for demanding environments.
