Frequently Asked Questions
What pitch and pin count does SFM-103-02-LM-D-A provide for high-density board-to-board connections?
SFM-103-02-LM-D-A is a 6-position dual-row socket strip with a 1.27mm (0.050") pitch, providing 3 pins per row in a 3×2 configuration. This fine pitch makes it suitable for high-density PCB layouts where board space is limited. The dual-row arrangement supports separate signal and power lines within a very compact 6-pin footprint.
How does the LM low-profile housing of SFM-103-02-LM-D-A benefit stacked PCB assemblies?
The LM suffix indicates a low-profile insulator height that minimizes the stack height between mated PCBs, typically enabling board-to-board separations of less than 4mm. This is critical in portable electronics and compact industrial modules where vertical clearance is at a premium. The reduced height also lowers the center of gravity of the mated pair, improving vibration resistance in harsh environments.
Is SFM-103-02-LM-D-A suitable for automated SMT reflow assembly at production volumes?
Yes, SFM-103-02-LM-D-A uses surface-mount termination pads compatible with standard 250°C peak reflow solder profiles. The SMT footprint places leads on a 1.27mm pitch grid that is supported by most PCB CAD libraries and paste stencil designs. At production volumes, the consistent coplanarity of SMT leads ensures high first-pass yield in automated pick-and-place reflow lines.
In what application categories is SFM-103-02-LM-D-A commonly specified as a mezzanine connector?
SFM-103-02-LM-D-A is frequently specified in telecommunications line cards, FPGA evaluation module expansions, and compact medical sensor interfaces where a reliable 6-pin 1.27mm socket is needed. Its gold-plated contacts maintain low contact resistance below 50mΩ even after repeated mating cycles, making it appropriate for removable modules requiring periodic servicing or field replacement.
