Frequently Asked Questions
What pin count and pitch does the SFM-119-L2-FM-D-A-K-TR provide for high-density mezzanine designs?
The SFM-119-L2-FM-D-A-K-TR offers 38 positions in a dual-row configuration at 0.050" (1.27 mm) pitch, with 19 contacts per row. This compact pitch and dual-row arrangement supports high signal density across a minimal board footprint, well suited for mezzanine connectors in embedded and portable electronics applications.
How does the flush-mount (-FM) feature of the SFM-119-L2-FM-D-A-K-TR benefit compact multi-board assemblies?
The -FM (flush mount) designation means the connector body sits very close to the PCB surface, reducing the mated stack height compared to standard variants. This is critical in slim portable devices, stacked PCB assemblies, and chassis-constrained designs where every millimeter of vertical clearance matters, and it minimizes mechanical stress on SMT solder joints during vibration.
For which signal types and data rates is the SFM-119-L2-FM-D-A-K-TR recommended?
The SFM-119-L2-FM-D-A-K-TR supports a broad range of signal types across its 38 pins at 1.27 mm pitch, including LVDS, CMOS, and single-ended digital signals operating at frequencies up to several GHz with proper PCB layout. Gold-plated contacts maintain low contact resistance, making the connector suitable for high-speed differential pairs and sensitive analog signals in FPGA and DSP designs.
When would a designer choose the SFM-119-L2-FM-D-A-K-TR over a larger SAMTEC SFM series socket for a daughter card interface?
A designer would select the 38-position SFM-119-L2-FM-D-A-K-TR when the interface requires fewer than 40 signal pins and board area is limited, as the smaller 38-pin body consumes less PCB real estate than 46- or 54-position variants. The 1.27 mm pitch and flush-mount profile further reduce footprint and stack height, making it the preferred choice for compact daughter cards, sensor modules, and portable measurement instruments.
