Frequently Asked Questions
How many signal positions does SFM-122-02-SM-D-LC provide at its 0.050" pitch?
SFM-122-02-SM-D-LC provides 44 positions in a dual-row layout at 0.050" (1.27 mm) pitch, with 22 pins per row. This fine-pitch dual-row configuration delivers 44 signal or power connections in a compact PCB footprint, making it highly suitable for mezzanine card stacking, FPGA module connections, and other space-constrained high-density board-to-board interconnect applications.
For a multi-gigabit backplane application, what advantage does the LC shielding in SFM-122-02-SM-D-LC offer?
The LC (low-crosstalk) shielding in SFM-122-02-SM-D-LC isolates adjacent signal pins at 0.050" (1.27 mm) pitch, reducing inductive and capacitive coupling that degrades high-speed signal quality. In multi-gigabit backplane or mezzanine card applications where 44 signal paths operate simultaneously, the low-crosstalk design maintains eye diagram integrity and reduces bit error rates compared to standard unshielded 0.050" pitch connectors.
When should a designer choose SFM-122-02-SM-D-LC over a 0.100" pitch connector for a board-to-board link?
A designer should choose SFM-122-02-SM-D-LC over a 0.100" pitch connector when board space is constrained and a high pin count is needed. With 44 positions at 0.050" (1.27 mm) pitch, SFM-122-02-SM-D-LC occupies half the board length of an equivalent 0.100" pitch 44-position connector. The trade-off is that fine-pitch assembly requires more precise pick-and-place placement, but the low-crosstalk shielding also enables better high-speed signal performance.
Is SFM-122-02-SM-D-LC suitable for use in aerospace or defense electronics with demanding reliability requirements?
Yes, SFM-122-02-SM-D-LC is positioned as a high-reliability connector series from SAMTEC, making it well-suited for aerospace and defense electronics. Its 44-position 0.050" (1.27 mm) pitch contacts with low-crosstalk shielding support reliable signal routing in avionics data buses, military embedded computing modules, and ruggedized communications equipment where consistent performance across extended temperature ranges and mechanical vibration is required.
