What are the key features of SFM-123-T2-FM-D-A-K?
- 46-position dual-row socket strip at 0.050" (1.27 mm) pitch for high-density SMT mezzanine interconnects
- Gold-plated contacts providing low contact resistance and reliable performance over 30+ mating cycles
- Surface mount footprint compatible with standard reflow soldering at up to 260°C for automated assembly
What is SFM-123-T2-FM-D-A-K used for?
The SFM-123-T2-FM-D-A-K is designed for mezzanine and daughter-card interconnects in telecommunications, industrial automation, and embedded computing platforms requiring 46-signal high-density connections. Its 0.050" pitch accommodates parallel bus architectures in FPGA evaluation boards and multi-channel analog front-end modules. The connector is also used in compact military electronics and avionics systems where board space is critical and connector reliability must be maintained across extreme temperature cycles.

Frequently Asked Questions
How many positions does the SFM-123-T2-FM-D-A-K provide and at what pitch?
The SFM-123-T2-FM-D-A-K offers 46 positions in a dual-row arrangement with a 0.050" (1.27 mm) pitch. This high-density layout allows 46 signal connections in roughly half the board length needed by a comparable 0.100" pitch connector, making it ideal for compact mezzanine designs.
For which FPGA daughter-card designs does the SFM-123-T2-FM-D-A-K provide the best fit?
FPGA FMC (FPGA Mezzanine Card) and custom daughter-card designs with 32 to 46 signal lanes benefit most, as the 0.050" pitch accommodates parallel 32-bit buses plus power and ground at 46 total positions. The gold-plated contacts support signal frequencies up to several hundred MHz while maintaining impedance continuity across the mating interface.
What differentiates the FM termination style in SFM-123-T2-FM-D-A-K from standard SMT tails?
The FM (flat mount) termination places solder tails flush against the PCB surface in a coplanar arrangement, reducing total connector height by approximately 0.3 mm compared to J-bend SMT tails. This ultra-low-profile mounting is critical for stackup-sensitive designs where the gap between mezzanine boards is less than 4 mm, such as compact server blades and ruggedized military electronics.
