Frequently Asked Questions
How many positions and rows does the SFM-149-L2-SM-D-A-P-TR provide, and what is its contact pitch?
The SFM-149-L2-SM-D-A-P-TR provides 98 total positions arranged in 2 rows of 49 contacts each, on a 0.050" (1.27 mm) pitch. This configuration delivers a high pin density within a compact surface mount footprint, supporting broad parallel signal buses in space-constrained PCB designs.
What soldering process and temperature profile is recommended for the SFM-149-L2-SM-D-A-P-TR?
The SFM-149-L2-SM-D-A-P-TR is designed for standard SMT reflow soldering, tolerating peak reflow temperatures up to 260°C. The integrated press-fit retention clips hold the connector in place during reflow without adhesive, ensuring consistent solder joint formation across all 98 positions in a single pass.
In which high-speed signal integrity applications is the SFM-149-L2-SM-D-A-P-TR commonly used?
This 98-position connector is commonly deployed in FPGA mezzanine cards, high-speed line card backplanes, and modular test instruments requiring wide 49-signal-per-row buses at 1.27 mm pitch. Gold-plated contacts minimize contact resistance, supporting signal speeds suitable for multi-gigabit serial and parallel interfaces in industrial and telecom systems.
When should the SFM-149-L2-SM-D-A-P-TR be selected over a lower pin-count SFM variant?
Choose the SFM-149-L2-SM-D-A-P-TR when your design requires 98 positions (49 pins per row) at 0.050" pitch in a single surface mount connector, avoiding the added height and complexity of using two smaller connectors in series. This is particularly valuable for FPGA daughter cards or memory expansion modules needing 98-pin data or address buses in a single footprint.
