Frequently Asked Questions
What contact plating does the SFM-105-02-S-D-A-P use and how does it affect reliability?
The SFM-105-02-S-D-A-P features 30 µin gold over 50 µin nickel contact plating. The thick gold finish provides excellent corrosion resistance and maintains low contact resistance below 20 mΩ through hundreds of mating cycles, which is critical for high-reliability applications in industrial and defense electronics.
What is the pitch and position count of the SFM-105-02-S-D-A-P, and how compact is the package?
The SFM-105-02-S-D-A-P provides 10 positions in a dual-row layout at 0.050" (1.27 mm) pitch, with a body measuring approximately 0.375" long x 0.185" deep x 0.145" wide. This compact form factor is ideal for high-density PCB interconnects where 0.100" pitch connectors would consume too much board area.
What does the positioning pin (P suffix) provide in the SFM-105-02-S-D-A-P during assembly?
The positioning pin (P suffix) is a mechanical feature that inserts into a corresponding hole in the PCB, preventing the connector from shifting or rotating during reflow soldering at temperatures up to 260°C. This ensures the 0.050" pitch contacts are accurately aligned to PCB pads, reducing tombstoning and solder bridging defects in automated SMT assembly.
For which board-to-board applications is the SFM-105-02-S-D-A-P a preferred choice over higher-pitch alternatives?
The SFM-105-02-S-D-A-P is preferred when PCB real estate is constrained and at least 10 signal connections are needed at 0.050" pitch, such as in small form-factor compute modules, FPGAs daughter cards, and RF front-end boards. At 0.050" pitch, the connector occupies roughly half the PCB length of an equivalent 0.100" pitch 10-position socket.
