Frequently Asked Questions
What polarization feature does the SFM-135-02-STL-D-A-K-TR provide and why is it important?
The SFM-135-02-STL-D-A-K-TR includes polarization that physically prevents incorrect mating orientation across its 70 positions at 0.050 inch pitch, protecting sensitive circuits from reverse-connection damage during assembly and field maintenance of high-density board stacking systems.
What contact finish does the SFM-135-02-STL-D-A-K-TR use on its termination, and how does it affect soldering?
The connector uses tin/lead over nickel barrier contact termination, which provides excellent solderability for SMT reflow processes and corrosion resistance at the interface, ensuring reliable 70-position solder joints on the PCB during standard reflow soldering assembly.
What factory lead time should procurement teams expect for the SFM-135-02-STL-D-A-K-TR?
The SFM-135-02-STL-D-A-K-TR carries a factory lead time of approximately 5 weeks and 5 days, meaning procurement teams should plan orders well ahead for production runs and consider safety stock for programs using this 70-position 0.050 inch pitch socket strip.
How does the 70-position count of SFM-135-02-STL-D-A-K-TR compare to smaller variants in the SFM series?
With 70 positions at 0.050 inch pitch, the SFM-135 provides 10 more contacts than the 60-position SFM-130 and 22 more than the 48-position SFM-124, making it the appropriate choice when interface buses exceed 60 signals without stepping up to a different connector series.
