Frequently Asked Questions
What does the L2 designator mean for the SFM-126-L2-S-D-A-K-TR and how does it affect PCB layout?
The L2 designator indicates an extended tail length compared to the standard L1 termination. For the 52-position, 1.27 mm pitch SFM-126-L2-S-D-A-K-TR, this extended tail increases solder joint height, improving mechanical compliance and reducing solder joint stress during thermal cycling on rigid PCB assemblies.
How many signal positions are available on the SFM-126-L2-S-D-A-K-TR connector?
The SFM-126-L2-S-D-A-K-TR provides 52 positions in a dual-row surface-mount configuration at 0.050 inch (1.27 mm) pitch, allowing up to 52 simultaneous signal or mixed signal-and-power connections across the two rows, suitable for high-density board-to-board interface designs.
Can the SFM-126-L2-S-D-A-K-TR be used in automated high-volume assembly lines?
Yes, the SFM-126-L2-S-D-A-K-TR is packaged in tape-and-reel (TR) format, making it fully compatible with automated pick-and-place equipment and standard SMT reflow soldering at peak temperatures up to 260 °C, enabling efficient high-volume production of boards featuring the 52-pin dual-row connector.
What types of electronic systems benefit from the 52-position dual-row SFM-126-L2-S-D-A-K-TR?
Embedded computing platforms, FPGA mezzanine cards, industrial fieldbus interface boards, and telecom line card assemblies benefit from the 52-position, 1.27 mm pitch dual-row configuration of this connector, which provides high signal density and mechanical reliability in a compact SMT footprint.
