Frequently Asked Questions
What pitch and pin count does the SFM-118-L2-F-D provide for board-level interconnections?
The SFM-118-L2-F-D features a 0.050 inch (1.27 mm) pitch with 36 positions arranged in a dual-row configuration, giving 18 pins per row. This tight pitch and dual-row layout allows designers to route a high number of signals through a small PCB footprint, making it ideal for compact electronic assemblies where board space is at a premium.
Which surface mount processes are compatible with the SFM-118-L2-F-D socket strip?
The SFM-118-L2-F-D is a surface mount connector with a body depth of 0.185 inches and breadth of 0.145 inches, compatible with standard SMT reflow soldering processes. Its tin termination finish with nickel barrier supports solder paste application and withstands reflow temperatures typical of lead-free assembly profiles, making it suitable for automated pick-and-place production lines.
How do the gold flash mating contacts on the SFM-118-L2-F-D compare to standard tin contacts for signal reliability?
Gold flash mating contacts on the SFM-118-L2-F-D provide superior corrosion resistance and lower contact resistance compared to plain tin contacts, particularly important for low-voltage signal lines where a few milliohms difference matters. Gold finish also extends the mating cycle durability, making the connector reliable in instrumentation and high-reliability board interconnection applications with repeated insertions.
Can the SFM-118-L2-F-D be used in high-vibration or aerospace environments?
Yes, the SFM-118-L2-F-D is designed as a high-reliability socket strip suitable for demanding environments including instrumentation and aerospace-adjacent applications. Its dual-row 36-pin surface mount design with nickel-barrier tin termination and gold-flash mating contacts provides stable electrical performance. Designers should verify the specific vibration and temperature ratings from the SAMTEC SFM series datasheet before deployment in safety-critical systems.
