What are the key features of SFM-122-02-H-D-A-P-TR?
- 44-position dual-row surface-mount socket on 0.050 inch (1.27 mm) pitch delivering 22 contacts per row in minimal PCB area
- Anti-solder-wicking (A suffix) contact design prevents flux from migrating into the mating zone during reflow soldering
- Polarized (P suffix) housing ensures correct orientation and prevents reverse mating on fine-pitch socket arrays
- Tape-and-reel (TR) packaging supports high-speed automated pick-and-place assembly in volume production
What is SFM-122-02-H-D-A-P-TR used for?
The SFM-122-02-H-D-A-P-TR is designed for high-density mezzanine and daughter card sockets in embedded computing, FPGA evaluation platforms, and telecommunications line cards where 44 signal or power lines must pass through a single 0.050 inch pitch interface. The anti-solder-wicking contacts protect signal integrity in fine-pitch reflow processes, while the polarized housing eliminates reverse-insertion defects during PCB assembly. Tape-and-reel delivery makes this socket strip efficient for high-volume SMT production runs.

Frequently Asked Questions
How many contact positions are in each row of the SFM-122-02-H-D-A-P-TR, and what is the total connector span?
The SFM-122-02-H-D-A-P-TR has 44 total positions split into 22 contacts per row on a 0.050 inch (1.27 mm) pitch. The mated row length spans approximately 1.1 inches (27.94 mm), allowing designers to carry 44 independent signals or mixed power and signal lines in a footprint about half the size of an equivalent 0.100 inch pitch connector, which is critical for compact embedded computing and instrumentation boards.
How does the anti-solder-wicking feature protect the SFM-122-02-H-D-A-P-TR during reflow assembly?
The anti-solder-wicking (A) design uses a contact geometry barrier that physically prevents molten solder flux from traveling up the 0.050 inch pitch contact tine by capillary action during lead-free reflow at temperatures up to 260 °C. Without this feature, flux contamination inside a fine-pitch socket can increase contact resistance by several ohms and cause intermittent failures in high-speed differential signal paths operating at 1 Gbps or above.
When is SFM-122-02-H-D-A-P-TR a better choice than a 0.100 inch pitch socket strip for an FPGA module design?
The 0.050 inch pitch of the SFM-122-02-H-D-A-P-TR provides the same 44-position count in roughly half the PCB row length compared to a 0.100 inch alternative. For FPGA modules where I/O density at the board edge exceeds 40 pins and board width is constrained to under 35 mm, this fine-pitch socket allows the full 44-signal interface to fit without requiring a second connector row or a wider module PCB, reducing both cost and form factor simultaneously.
