Frequently Asked Questions
What pin count and pitch does the SFM-122-02-STL-D-A-K-TR offer, and how does this suit FPGA daughter card designs?
The SFM-122-02-STL-D-A-K-TR provides 44 positions in a dual-row layout at 1.27 mm (0.050") pitch, accommodating 44 signal or power lines in a footprint less than 30 mm long. This pitch density is well matched to FPGA daughter cards and high-speed mezzanine modules where routing 44 signals at 2.54 mm pitch would require prohibitively long connectors on constrained PCB layouts.
How does the SFM-122-02-STL-D-A-K-TR perform in high-vibration industrial environments compared to standard socket strips?
SAMTEC SFM-series high-reliability socket strips are engineered with robust contact retention forces exceeding standard commercial grades, maintaining electrical contact resistance below 20 mΩ across 44 positions even under vibration profiles specified for industrial and aerospace equipment. Their gold-plated contacts also resist fretting corrosion that commonly degrades tin-contact sockets in high-vibration environments over thousands of operating hours.
When is the SFM-122-02-STL-D-A-K-TR preferable to a through-hole 44-pin socket for a production board design?
The SFM-122-02-STL-D-A-K-TR's SMT footprint eliminates the need for 44 drilled holes, reducing PCB fabrication cost and enabling double-sided component placement on the board. For production volumes above 500 units, automated pick-and-place installation of the surface mount socket also lowers assembly labor cost compared to manual through-hole insertion, while the 1.27 mm pitch saves 50% of the linear board edge space required by equivalent 2.54 mm through-hole sockets.
