Frequently Asked Questions
How many positions does SFM-123-L2-FM-D-K-TR provide and at what pitch spacing?
The SFM-123-L2-FM-D-K-TR provides 46 total positions in a dual-row arrangement at 0.050" (1.27 mm) pitch, delivering high signal density for board-to-board and mezzanine connector applications in compact surface mount PCB designs.
For embedded computing daughter cards running at industrial temperatures, how does SFM-123-L2-FM-D-K-TR perform?
The SFM-123-L2-FM-D-K-TR's high-reliability gold-plated contacts and surface mount construction maintain stable electrical performance at industrial operating temperatures from -55°C to +125°C, making it dependable for embedded daughter cards in harsh environments.
How does the SFM-123-L2-FM-D-K-TR's 1.27 mm pitch compare to 2.54 mm pitch alternatives for space-constrained PCB layouts?
At 1.27 mm pitch, the SFM-123-L2-FM-D-K-TR occupies roughly half the footprint length compared to a 2.54 mm pitch 46-position header, enabling designers to fit 46 signal connections in much tighter PCB areas — ideal for compact instrumentation and communications modules.
