What are the key features of SFM-109-T2-H-D-LC?
- 18-position dual-row layout on 0.050 inch (1.27 mm) pitch for ultra-high-density PCB interconnects
- High-reliability contact design with low-crosstalk (LC) option for signal integrity in demanding applications
- Surface-mount termination enabling automated reflow assembly on fine-pitch PCB footprints
What is SFM-109-T2-H-D-LC used for?
The SFM-109-T2-H-D-LC is intended for high-reliability mezzanine board stacking and module-on-board interconnects in defense, aerospace, and high-speed communications equipment. Its 0.050 inch pitch and dual-row layout maximize contact density while the low-crosstalk contact geometry preserves signal integrity at multi-GHz data rates. Engineers use this socket in FPGA daughter cards, RF modules, and embedded computing platforms where space and signal performance are jointly critical.

Frequently Asked Questions
What pitch and row configuration does the SFM-109-T2-H-D-LC use, and how does that affect board density?
The SFM-109-T2-H-D-LC uses a 0.050 inch (1.27 mm) pitch with a dual-row arrangement totaling 18 positions, allowing a very compact PCB footprint of roughly 4.5 mm x 2.54 mm that doubles contact count compared with single-row alternatives at the same body length.
What does the LC (low-crosstalk) designation mean for high-speed signal applications?
The LC designation indicates that the contact geometry and housing are engineered to minimize electromagnetic coupling between adjacent signal lines. This is critical when routing differential pairs or high-speed single-ended signals above 1 GHz, such as LVDS, PCIe, or SerDes lanes, where standard contacts would introduce unacceptable inter-pair crosstalk and timing jitter.
Is SFM-109-T2-H-D-LC suitable for defense or aerospace qualification programs?
Yes. SAMTEC SFM-series socket strips with high-reliability (H) contact plating are commonly used in MIL-grade or space-class programs. The surface-mount termination survives the 260°C reflow profiles typical in lead-free assembly, and the high-reliability contact rating supports extended operating temperatures from -55°C to +125°C as required by many defense qualification standards.
