Frequently Asked Questions
What pitch and position count does SFM-109-L2-SM-D-LC offer, and how does it mount?
The SFM-109-L2-SM-D-LC offers 18 positions in a dual-row layout with 0.050" (1.27 mm) pitch, mounted via surface mount technology (SMT). The L2 solder tail configuration supports standard reflow soldering processes up to 260°C peak temperature, enabling high-throughput automated assembly on compact PCBs.
Which SAMTEC mating headers are compatible with SFM-109-L2-SM-D-LC for board-to-board stacking applications?
The SFM-109-L2-SM-D-LC is designed to mate with SAMTEC TFM and SFM series headers at 0.050" (1.27 mm) pitch in dual-row configurations. This compatibility enables board-to-board stacking in FPGA mezzanine, FMC, and high-density module applications where 18-position dual-row socket connections are required across multiple PCB heights.
Why is LCP housing material preferred for high-reliability socket strips in demanding environments?
LCP (liquid crystal polymer) housing in SFM-109-L2-SM-D-LC provides exceptional dimensional stability, low moisture absorption below 0.02%, and thermal resistance up to 260°C, making it ideal for demanding environments including aerospace and medical electronics. LCP outperforms standard nylon or PBT housings in applications subject to harsh chemical exposure, elevated temperatures, and multiple reflow cycles.
