What are the key features of SFM-122-T2-FM-D-A-P-TR?
- 44-position dual-row configuration at 0.050 inch (1.27 mm) pitch enabling high-density signal interconnect in compact PCB designs
- Gold-plated (A) contacts with female-mount (FM) tail for low contact resistance below 20 milliohms and extended mating cycle life
- Polarized shroud (P) housing prevents mis-mating and protects 44 contacts during repeated field-service insertions
- Tape-and-reel (TR) packaging for seamless integration into high-volume automated pick-and-place SMT assembly lines
What is SFM-122-T2-FM-D-A-P-TR used for?
The SFM-122-T2-FM-D-A-P-TR is designed for high-density mezzanine and board-to-board interconnect in FPGA daughter cards, communications line modules, and test-and-measurement platforms requiring 44 signal connections at 0.050 inch pitch. Its gold-plated contacts ensure stable contact resistance in high-cycle applications such as hot-swap and field-replaceable modules. The shrouded polarized housing adds keying protection in dense PCB layouts where mis-mating would damage fine-pitch contacts.

Frequently Asked Questions
What is the position count and pitch of the SFM-122-T2-FM-D-A-P-TR, and how does that affect PCB layout?
The SFM-122-T2-FM-D-A-P-TR offers 44 positions in a dual-row layout at 0.050 inch (1.27 mm) pitch, which reduces connector length by roughly 50% compared to the same 44-position count at 0.100 inch pitch, freeing PCB area for routing and decoupling capacitors in compact high-speed designs.
How does the shrouded P housing on the SFM-122-T2-FM-D-A-P-TR protect the connector in a production environment?
The P shroud encloses all 44 fine-pitch contacts behind a plastic wall with a polarization key, preventing mis-mating during automated board assembly and manual handling, which is critical at 0.050 inch pitch where a single-row offset would short-circuit adjacent signal contacts.
Which high-speed data applications benefit from the gold-plated contacts of the SFM-122-T2-FM-D-A-P-TR?
FPGA mezzanine boards, PCIe add-in card adapters, and test-and-measurement modules operating serial lanes at data rates above 1 Gbps benefit from the gold-plated (A) contacts, which maintain contact resistance below 20 milliohms across 500 or more mating cycles to preserve signal integrity at 50 ohm or 100 ohm controlled-impedance routing.
Can the SFM-122-T2-FM-D-A-P-TR be processed through a standard no-clean reflow profile?
Yes, the surface-mount SFM-122-T2-FM-D-A-P-TR is rated for standard lead-free reflow soldering with a peak temperature up to 260 degrees C, and the tape-and-reel (TR) packaging is compatible with 8 mm or 12 mm feeder widths on pick-and-place machines for high-volume production runs.
