What are the key features of SFM-146-L2-SM-D-A-K-TR?
- 92-position dual-row layout with 0.050" (1.27 mm) pitch for maximum signal density in SMT board interconnects
- Gold-plated high-reliability contacts ensure consistent low-resistance mating across extended operating life
- Surface mount termination supports standard pick-and-place and reflow solder assembly processes
- Dual-row configuration provides 46 positions per row, optimizing pin count per unit connector length on PCB
What is SFM-146-L2-SM-D-A-K-TR used for?
The SFM-146-L2-SM-D-A-K-TR is deployed in high-density mezzanine board-to-board interconnect systems requiring 92 signal positions within a compact 1.27 mm pitch SMT footprint. It is used in FPGA expansion boards, server backplane daughter cards, and high-channel-count data acquisition modules where maximizing signal count per connector is critical. Its dual-row layout also supports mixed signal and power distribution across the 92 contacts in industrial and embedded computing platforms.

Frequently Asked Questions
How many signal positions does the SFM-146-L2-SM-D-A-K-TR provide and at what pitch?
The SFM-146-L2-SM-D-A-K-TR provides 92 positions in a dual-row layout with a 0.050" (1.27 mm) pitch, giving 46 contacts per row. This high contact count in a compact footprint supports dense signal routing for FPGA, processor, and multi-channel I/O interfaces on mezzanine boards where PCB area per connector is strictly limited.
What termination style does the SFM-146-L2-SM-D-A-K-TR use, and how does that affect PCB fabrication?
The SFM-146-L2-SM-D-A-K-TR uses surface mount (SMT) termination, eliminating the need to drill 92 through-holes in the PCB. This reduces fabrication cost and board thickness constraints while enabling fine-pitch escape routing on inner layers. The 1.27 mm pitch SMT pads are compatible with standard pick-and-place reflow assembly for high-volume production runs.
In which high-density interconnect applications does the SFM-146-L2-SM-D-A-K-TR excel?
With 92 positions at 0.050" pitch, the SFM-146-L2-SM-D-A-K-TR is ideal for FPGA daughter card sockets, server compute module interfaces, and multi-channel analog or mixed-signal backplanes. It handles up to 92 simultaneous signal connections including LVDS pairs, SPI buses, and power rails in industrial embedded systems where connector density must exceed 70 contacts per connector.
How does the 92-position SFM-146-L2-SM-D-A-K-TR compare to a standard 2 mm pitch dual-row connector for the same application?
At 0.050" (1.27 mm) pitch, the SFM-146-L2-SM-D-A-K-TR occupies about 37% less PCB length than a 2 mm pitch dual-row connector carrying the same 92 positions. This space saving is critical in blade server and embedded computing designs where multiple high-density connectors must coexist within a 100 mm card width, leaving room for decoupling capacitors and signal routing channels.
