Frequently Asked Questions
How many signal contacts does the SFM-123-L2-SM-D-A-K-TR provide, and what is its pitch?
The SFM-123-L2-SM-D-A-K-TR has 46 positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch, yielding 92 individual contact points per connector. This high-density layout supports complex signal routing on compact PCBs without sacrificing contact reliability or signal integrity.
For a high-speed FPGA daughter card requiring 80+ signal lines, how does the SFM-123-L2-SM-D-A-K-TR compare to a single-row alternative?
The SFM-123-L2-SM-D-A-K-TR's dual-row arrangement at 0.050" pitch accommodates 92 contacts in roughly half the board length of an equivalent single-row connector, saving approximately 58 mm of edge length for 80-signal applications. This space savings is critical in FPGA daughter card designs where PCB real estate is tightly constrained.
What manufacturing advantages does the K-TR tape-and-reel packaging offer for the SFM-123-L2-SM-D-A-K-TR in high-volume production?
The K-TR tape-and-reel format packages the SFM-123-L2-SM-D-A-K-TR on industry-standard carrier tape for direct use with automated pick-and-place machines, reducing manual handling errors and enabling placement rates exceeding 5,000 parts per hour on modern SMT lines. It also preserves connector planarity and protects gold-plated contacts during transit.
