Frequently Asked Questions
How many pins per row does the SFM-137-T2-SM-D-A-K provide in its dual-row layout?
The SFM-137-T2-SM-D-A-K has 74 total positions in a dual-row configuration at 0.050" (1.27 mm) pitch, giving 37 pins per row, which provides a wide signal bus for FPGA mezzanine boards and data acquisition expansion modules that need dense connectivity in a compact SMT package.
Can the SFM-137-T2-SM-D-A-K handle power and signal simultaneously on the same connector?
Each gold-plated contact in the SFM-137-T2-SM-D-A-K is rated at 1 A per pin, so selected pins can carry low-power supply rails while the remaining 74 contacts handle signal lines, making it practical for board-stacking designs that share a single 0.050" pitch connector for both signal and auxiliary power distribution at up to 1 A per contact.
What surface-mount assembly format does the SFM-137-T2-SM-D-A-K use and how does it affect pick-and-place compatibility?
The SFM-137-T2-SM-D-A-K uses surface-mount technology (SMT) termination in the T2 lead style, compatible with standard reflow soldering and pick-and-place assembly equipment, enabling consistent automated placement of the 74-pin connector on PCBs for high-volume production of industrial and computing systems.
