What are the key features of SFM-102-L2-S-D-LC?
- Ultra-fine 0.050 inch (1.27 mm) pitch dual-row layout fits 4 positions into half the board space of standard 0.100 inch connectors
- High-reliability socket strip construction with gold-plated contacts ensures low insertion loss and long-term corrosion resistance in demanding environments
- Surface mount footprint with LC (low crosstalk) designation supports high-speed signal integrity applications up to several GHz
What is SFM-102-L2-S-D-LC used for?
The SFM-102-L2-S-D-LC is ideal for compact board-to-board mezzanine connections in high-density electronics such as FPGA daughter cards, RF modules, and embedded computing platforms. Its 0.050-inch pitch reduces footprint by up to 75% compared to 0.100-inch alternatives, enabling tighter component placement in space-constrained designs. The low-crosstalk construction maintains signal integrity at high data rates, making it suitable for multi-gigabit SerDes and DDR memory interface applications.

Frequently Asked Questions
What pitch does the SFM-102-L2-S-D-LC use, and how does that compare to standard 0.100-inch connectors in board space savings?
The SFM-102-L2-S-D-LC uses a 0.050 inch (1.27 mm) pitch, which is half the spacing of standard 0.100 inch connectors, allowing designers to achieve the same number of contact positions in approximately 50% of the board area, a significant advantage in high-density PCB layouts with over 200 signals per square inch.
For which high-speed signal applications is the low-crosstalk (LC) variant of the SFM-102-L2-S-D-LC particularly suitable?
The LC (low crosstalk) designation makes this connector well-suited for differential pair routing at data rates of 5 Gbps to 10 Gbps, including PCIe, USB 3.x, and LVDS interfaces, where adjacent contact coupling must remain below -40 dB to avoid bit errors in sensitive signal chains.
How does the dual-row socket configuration of the SFM-102-L2-S-D-LC affect mating with SAMTEC pin headers?
The dual-row socket mates with SAMTEC's SFM-compatible pin header series on a shared 0.050 inch pitch, providing 4 total positions with 8 signal contacts, and the L2 tail length variant ensures a controlled insertion depth of approximately 2.4 mm for reliable solder joint formation on standard 1.6 mm PCB substrates.
Can the SFM-102-L2-S-D-LC be used in automated SMT reflow assembly, and what temperature rating does it support?
Yes, the surface mount configuration is fully compatible with standard SMT reflow soldering at peak temperatures up to 260°C for 30 seconds per J-STD-020, and the high-reliability construction maintains contact resistance below 20 milliohms after 500 mating cycles, ensuring long-term performance in production environments.
