Frequently Asked Questions
How does the gold flash contact finish on SFM-120-T2-F-D affect mating reliability compared to standard tin contacts?
Gold flash mating contacts on SFM-120-T2-F-D provide a hard, oxidation-resistant surface that maintains low contact resistance below 20 milliohms across hundreds of mating cycles. Compared to standard tin-only contacts, gold flash significantly reduces the risk of fretting corrosion in applications subject to vibration or temperature cycling between -40°C and +85°C, ensuring consistent signal integrity in the 40-position dual-row socket.
What is the mating pitch and position count of SFM-120-T2-F-D, and which standard headers does it mate with?
SFM-120-T2-F-D uses a 0.050 inch (1.27 mm) pitch dual-row layout with 40 total positions arranged in 2 rows of 20. It mates with standard 0.050 inch pitch dual-row pin headers of the same 20-per-row format, including SAMTEC's own TSW, MTMS, and FTSH series as well as compatible headers from other manufacturers maintaining the 1.27 mm pitch standard.
Can SFM-120-T2-F-D be used in high-cycle test fixture applications where the socket is mated repeatedly with DUT boards?
The SFM-120-T2-F-D is rated for high reliability with gold flash mating contacts designed to sustain multiple insertion cycles without significant contact resistance degradation. For test fixture applications requiring more than 500 mating cycles, buyers should confirm the exact cycle life rating from SAMTEC's datasheet and consider specifying the higher gold plating variant if cycling exceeds standard gold flash limits of approximately 100 to 200 cycles.
What PCB land pattern and reflow profile are recommended for SMT assembly of SFM-120-T2-F-D?
The SFM-120-T2-F-D SMT footprint follows SAMTEC's published land pattern for the SFM series with 0.050 inch (1.27 mm) dual-row pitch. The Tin (Sn) over Nickel (Ni) solder terminations are compatible with standard SAC305 lead-free solder paste and a peak reflow temperature of 245°C to 260°C. Designers should maintain a maximum of 2 reflow cycles to preserve contact plating integrity and housing material dimensional tolerance.
