What are the key features of SFM-146-T2-F-D-A-K?
- 92-position dual-row layout at 0.050" (1.27 mm) pitch provides 46 contacts per row, supporting dense signal interconnects in FPGA mezzanine and server daughtercard applications
- High-reliability gold-plated contact system maintains low contact resistance and consistent signal integrity over extended mating cycles in demanding board-to-board stacking environments
- Surface mount footprint with no-lead or tail configuration simplifies PCB design rules and enables co-planar soldering with other SMT components during reflow assembly
What is SFM-146-T2-F-D-A-K used for?
The SFM-146-T2-F-D-A-K is deployed in high-density FPGA mezzanine cards, network line cards, and industrial computing modules where 92 signal connections between stacked boards are needed at a 1.27 mm pitch. Its dual-row SMT format reduces the connector outline compared to through-hole alternatives, supporting compact multi-board stack architectures in rack-mount servers and ruggedized embedded systems. The high-reliability contact design ensures long service life in environments subject to thermal cycling and mechanical vibration.

Frequently Asked Questions
What is the total contact count and row configuration of the SFM-146-T2-F-D-A-K?
The SFM-146-T2-F-D-A-K has 92 contacts arranged in 2 rows at a 0.050" (1.27 mm) pitch, with 46 contacts per row. This contact density is well suited to FPGA mezzanine card standards and multi-gigabit backplane applications where routing dozens of differential signal pairs and power connections between boards requires a connector with high position count in a compact SMT footprint.
How does the 0.050" pitch of the SFM-146-T2-F-D-A-K compare to standard 0.100" pitch connectors in terms of board space savings?
At 0.050" (1.27 mm) pitch, the SFM-146-T2-F-D-A-K occupies roughly half the linear board space of an equivalent-count 0.100" (2.54 mm) pitch connector. For a 92-position dual-row connector, this translates to a contact field approximately 2.3 inches long at 0.050" pitch versus about 4.6 inches at 0.100" pitch, a significant area reduction on PCBs where connector placement competes with component routing channels.
Is the SFM-146-T2-F-D-A-K suitable for automated SMT assembly, and what soldering process does it support?
Yes, the SFM-146-T2-F-D-A-K uses a surface mount termination style compatible with standard automated reflow soldering at peak temperatures up to 260°C. Its SMT leads allow it to be placed by pick-and-place machines alongside other surface mount components, eliminating a separate through-hole soldering step and reducing assembly cost in volume production of FPGA boards and telecom line cards.
