Frequently Asked Questions
What is the pitch and row configuration of the SFM-109-L2-STL-D-A connector?
The SFM-109-L2-STL-D-A features a 0.050" (1.27 mm) pitch in a dual-row configuration, providing 18 total positions. This compact pitch enables high-density connections in space-constrained PCB designs, making it a popular choice for mezzanine and board-stacking applications requiring reliable signal transmission.
Which PCB assembly method is compatible with the SFM-109-L2-STL-D-A, and what are typical reflow temperature limits?
The SFM-109-L2-STL-D-A uses surface mount termination, making it compatible with standard SMT reflow soldering at temperatures up to 260°C. This allows automated placement and soldering in high-volume PCB assembly lines, reducing cost and improving repeatability versus through-hole alternatives.
In which high-reliability applications is the SAMTEC SFM-109-L2-STL-D-A typically deployed?
This connector is deployed in ruggedized industrial controls, military electronics, and test instrumentation requiring compact 18-position dual-row socket strips. Operating temperature ranges of -55°C to +125°C and high-reliability materials make it suitable for harsh environments found in aerospace, defense, and precision measurement systems.
How does the dual-row 18-position layout compare to single-row alternatives for PCB space savings?
By using a dual-row 18-position layout at 0.050" pitch, the SFM-109-L2-STL-D-A provides 18 contacts in roughly half the linear PCB footprint of a comparable single-row connector. This reduces board space by approximately 50% compared to single-row 18-pin solutions, which is critical in compact embedded designs.
