What are the key features of SFM-122-L2-F-D-A-P-TR?
- 44-position dual-row layout on 0.050" (1.27 mm) pitch provides 22 contacts per row for medium-density mezzanine board interconnects
- Low-profile L2 housing reduces board stack height to support tight inter-board clearances in compact embedded computing assemblies
- Polarization peg (P) prevents misoriented mating on dense PCBs with multiple adjacent connectors, reducing field assembly errors
- Tape-and-reel (TR) delivery enables seamless automated SMT pick-and-place production for medium and high-volume manufacturing
What is SFM-122-L2-F-D-A-P-TR used for?
The SFM-122-L2-F-D-A-P-TR is designed for medium-density mezzanine board-to-board connections in FPGA expansion cards, communications modules, and industrial automation systems requiring 44 signal contacts with keyed error-proof mating. The low-profile L2 design enables compact stacked PCB assemblies with clearances under 5 mm, suitable for ruggedized embedded systems. Tape-and-reel packaging streamlines high-volume SMT production for telecommunications and industrial electronics.

Frequently Asked Questions
How many contacts per row does the SFM-122-L2-F-D-A-P-TR provide, and what is the body length at 0.050" pitch?
The SFM-122-L2-F-D-A-P-TR has 44 total positions in a dual-row arrangement, providing 22 contacts per row on a 0.050" (1.27 mm) pitch. The body length is approximately 27.9 mm (22 positions × 1.27 mm). This makes it suitable for interfaces requiring between 33 and 44 signal connections, such as 32-bit parallel buses with additional handshake and power pins.
For an FPGA mezzanine card requiring 44 signal lines, how does the SFM-122 compare to a 40-position SFM-120 alternative?
The SFM-122 provides 4 additional positions (44 vs 40 total), adding approximately 5 mm to the body length to reach 27.9 mm versus 25.4 mm for SFM-120. If the design uses exactly 44 signals such as 32 data bits plus 8 address lines and 4 control signals, the SFM-122 avoids leaving any pins unconnected. Choosing SFM-120 would require routing 4 signals to a secondary connector, adding complexity. When the signal count is precisely 44, SFM-122 provides the cleanest single-connector solution.
What assembly advantages does the TR (tape-and-reel) format of SFM-122-L2-F-D-A-P-TR offer compared to tube-packaged connectors?
Tape-and-reel packaging allows the SFM-122-L2-F-D-A-P-TR to be fed directly into automated SMT pick-and-place machines at rates of several hundred parts per hour, eliminating manual placement. Standard reel sizes of 500 to 2000 pieces reduce feeder changeover frequency in high-volume runs. Tube-packaged connectors, by contrast, require manual loading and are better suited for prototyping or low-volume batches under 50 units.
