Frequently Asked Questions
How many positions does the SFM-149-L2-S-D-LC provide and how are they arranged?
The SFM-149-L2-S-D-LC provides 98 positions arranged in a dual-row configuration on a 0.050-inch (1.27 mm) pitch, giving designers 49 signal pairs within a compact surface-mount footprint suitable for high-density PCB layouts.
What PCB mounting style does the SFM-149-L2-S-D-LC use, and how does it affect assembly?
The connector uses surface-mount termination, which is compatible with standard SMT reflow soldering processes. This allows automated pick-and-place assembly at typical reflow temperatures of 260°C, reducing manufacturing cost and improving joint consistency versus through-hole alternatives.
In which high-reliability system designs is the SFM-149-L2-S-D-LC a practical choice?
The SFM-149-L2-S-D-LC suits FPGA daughter-card interconnects, backplane expansion modules, and industrial control boards where 98 contacts at 1.27 mm pitch are needed. Its gold-plated contacts maintain low resistance after thousands of mating cycles, making it suitable for test instrumentation requiring at least 500 mating cycle reliability.
What is the contact pitch of the SFM-149-L2-S-D-LC, and why does it matter for PCB layout?
The SFM-149-L2-S-D-LC uses a 0.050-inch (1.27 mm) pitch between adjacent contacts. This fine pitch enables high pin density, allowing 98 connections within roughly 62 mm of board length in a dual-row format, which is critical for space-constrained embedded and telecommunications designs.
