What are the key features of SFM-105-L2-F-D-LC?
- 10-position dual-row socket strip on 1.27 mm (0.050 inch) pitch providing 10 contacts in a footprint under 15 mm long for space-constrained SMT designs
- Low-clearance (-LC) variant minimizes the mated board-to-board separation, enabling stack heights below 5 mm in ultra-thin module assemblies
- High-reliability SFM contact system rated for repeated mating cycles with contact resistance below 20 milliohms after 30 insertion events
What is SFM-105-L2-F-D-LC used for?
The SFM-105-L2-F-D-LC is designed for ultra-compact board-to-board interconnects in wearable medical devices, miniature IoT sensor nodes, and portable instrumentation where a 10-position low-profile surface-mount socket must occupy minimal board area. Its low-clearance profile is critical in multi-board stack assemblies where the total product thickness must remain under 10 mm. The 1.27 mm pitch allows routing 10 mixed signal and power contacts within a connector body shorter than 15 mm, replacing multiple individual connectors in congested PCB layouts.

Frequently Asked Questions
How does the low-clearance (-LC) profile of the SFM-105-L2-F-D-LC affect the total mated stack height in a two-board module?
The -LC option reduces the board-to-board mated height to approximately 1.5 mm to 3 mm above each PCB surface, compared to 5 mm or more for a standard-clearance SFM variant. In a two-board module this can cut the total mated stack height by 4 mm or more, which is significant when the target enclosure constrains the full assembly to under 10 mm in thickness.
What is the signal bandwidth that the SFM-105-L2-F-D-LC can carry, and is it suitable for USB 2.0 high-speed signaling?
SAMTEC SFM-series connectors at 1.27 mm pitch are characterized for differential data rates up to several Gbps per pair, with -3 dB bandwidth typically above 3 GHz. USB 2.0 High Speed operates at 480 Mbps, well within this bandwidth, and the connector's contact geometry maintains characteristic impedance near 50 ohms to keep reflections below acceptable limits at USB 2.0 frequencies.
When would a designer choose the 10-position SFM-105-L2-F-D-LC over a larger 18-position or 34-position SFM variant?
The 10-position variant is the right choice when the interface between two boards requires 8 to 10 signals — for example, a 4-wire SPI bus plus chip select, power, and ground — and board area is severely constrained to under 15 mm along the connector axis. Using a smaller count reduces the connector footprint by approximately 50% compared to an 18-position strip, and eliminates unnecessary contacts that add parasitic capacitance to a high-speed bus.
How many mating cycles can the SFM-105-L2-F-D-LC sustain while maintaining reliable contact resistance, and what does this mean for module serviceability?
SAMTEC high-reliability SFM socket strips are rated for a minimum of 30 mating cycles with contact resistance maintained below 20 milliohms throughout. At one service intervention per quarter, this supports over 7 years of field replacements, which exceeds the expected lifespan of most portable and wearable consumer electronic products where 10-position board-to-board connectors are commonly used.
