Frequently Asked Questions
What position count and pitch does SFM-122-L2-LM-D-A-K offer for mezzanine interconnects?
SFM-122-L2-LM-D-A-K provides 44 total positions in a dual-row layout (22 per row) with a 1.27 mm (0.050 inch) pitch. This fine-pitch, dual-row configuration delivers high I/O density for mezzanine connections in aerospace, defense, and compact industrial modules.
How does the gold plating on SFM-122-L2-LM-D-A-K contribute to long-term reliability?
The gold-plated contacts on SFM-122-L2-LM-D-A-K maintain low contact resistance, typically below 30 mΩ, and resist oxidation even after thousands of insertion and withdrawal cycles. This reliability is critical for avionics, defense electronics, and medical equipment where connector failures are not tolerable.
Can SFM-122-L2-LM-D-A-K be assembled using standard SMT reflow processes?
Yes. SFM-122-L2-LM-D-A-K features a surface mount tail designed for reflow soldering at peak temperatures around 260 °C, consistent with IPC/JEDEC J-STD-020. Its SMT form factor supports automated pick-and-place placement in standard production lines, reducing assembly time for high-volume board runs.
What distinguishes SFM-122-L2-LM-D-A-K from standard-reliability SMT socket strips at the same pitch?
SFM-122-L2-LM-D-A-K is built to SAMTEC's high-reliability specification, using heavier gold plating and tighter mechanical tolerances compared to standard commercial-grade SMT strips at 1.27 mm pitch. This makes it a stronger choice for environments with wide temperature swings, mechanical shock, or vibration, such as airborne or industrial motion-control equipment.
