What are the key features of SFM-148-L2-STL-D-A-P-TR?
- 96 positions on a 1.27mm pitch dual-row layout achieving maximum I/O density for compact SMT boards
- High-reliability socket construction with precision contacts rated for extended mating cycles in harsh environments
- Tape-and-reel packaging enabling fully automated pick-and-place SMT assembly
What is SFM-148-L2-STL-D-A-P-TR used for?
The SFM-148-L2-STL-D-A-P-TR is engineered for high-cycle mezzanine board connections in FPGA daughter cards, embedded processor modules, and aerospace or defense electronics where 96 signals must be reliably transferred across a 1.27mm grid. Its high-reliability rating and surface-mount configuration ensure stable electrical performance across temperature extremes and mechanical stress conditions. The tape-and-reel format supports high-volume automated assembly without compromising placement accuracy.

Frequently Asked Questions
What are the position count and pitch of the SFM-148-L2-STL-D-A-P-TR socket strip?
The SFM-148-L2-STL-D-A-P-TR provides 96 positions in a dual-row arrangement with a 1.27mm (0.050 inch) pitch, giving designers a very high-density surface-mount socket capable of routing up to 96 signal or mixed-voltage lines within a compact PCB footprint.
How does the SFM-148-L2-STL-D-A-P-TR's 1.27mm pitch help in FPGA mezzanine card designs?
At 1.27mm pitch the SFM-148-L2-STL-D-A-P-TR allows 96 contacts to fit in roughly the same linear space a 2.54mm connector would need for only 48, enabling FPGA FMC or custom mezzanine cards to break out high lane-count SerDes interfaces, LVDS buses, and power rails simultaneously without expanding board area.
What reliability characteristics should designers expect from the SFM-148-L2-STL-D-A-P-TR in aerospace applications?
The high-reliability designation on the SFM-148-L2-STL-D-A-P-TR implies gold-plated contacts for low and stable contact resistance, precision housing tolerances for consistent mating alignment, and a mating cycle life typically rated at 100 cycles or more, all critical for avionics and defense modules subject to vibration, shock, and wide temperature swings from -55°C to +125°C.
Can the SFM-148-L2-STL-D-A-P-TR be used as an alternative to a 2.54mm pitch socket strip with fewer positions?
Yes, if the application allows a PCB redesign, replacing a 2.54mm socket with the SFM-148-L2-STL-D-A-P-TR at 1.27mm pitch and 96 positions enables doubling I/O density or shrinking the connector footprint by approximately 50%, at the cost of tighter PCB trace routing and smaller via clearances required by the finer 1.27mm grid.
