What are the key features of SFM-122-T2-F-D-A-P-TR?
- 44-position dual-row SMT socket at 0.050 inch (1.27 mm) pitch enabling dense 22-per-row signal routing on compact PCB footprints
- Gold-plated (A suffix) contacts providing low contact resistance below 20 mΩ and consistent performance over 500+ mating cycles
- Tape-and-reel (TR) packaging supporting automated pick-and-place SMT assembly with reflow compatibility up to 260°C peak temperature
What is SFM-122-T2-F-D-A-P-TR used for?
The SAMTEC SFM-122-T2-F-D-A-P-TR is suitable for mezzanine board interconnects, FPGA daughter cards, and embedded processor expansion modules that require 44 signal connections at 0.050 inch pitch. The gold-plated dual-row format supports high-speed differential pairs, parallel data buses, and mixed power-and-signal configurations in industrial computing and telecommunications hardware. Its tape-and-reel packaging enables efficient automated SMT assembly in medium to high-volume production runs.

Frequently Asked Questions
How many positions per row does the SFM-122-T2-F-D-A-P-TR offer at its 0.050 inch pitch?
The SFM-122-T2-F-D-A-P-TR provides 44 total positions in a dual-row layout at 0.050 inch (1.27 mm) pitch, giving 22 contacts per row. This arrangement supports parallel bus widths of up to 16-bit data plus address and control lines, or 22 differential signal pairs per row, making it versatile for FPGA and DSP expansion board designs.
What soldering profile is compatible with the SFM-122-T2-F-D-A-P-TR for SMT assembly?
The SFM-122-T2-F-D-A-P-TR is rated for SMT reflow soldering with a peak temperature of 260°C, compatible with SAC305 lead-free solder per IPC/JEDEC J-STD-020. The tape-and-reel (TR) packaging supports standard automated pick-and-place equipment, enabling consistent solder joint formation across all 44 positions in a single reflow pass on industrial assembly lines.
When should a designer choose the 44-position SFM-122 over a lower-count SFM socket strip?
A 44-position SFM-122-T2-F-D-A-P-TR is preferred over lower-count SFM variants when the design requires routing a 32-bit data bus plus 12 control or power signals across a single connector pair. Consolidating 44 connections into one dual-row 0.050 inch pitch socket reduces PCB routing complexity and improves ground plane integrity compared to using two 22-position connectors in series.
How does gold plating on the SFM-122-T2-F-D-A-P-TR contacts benefit high-frequency signal applications?
The gold (Au) contact finish on the SFM-122-T2-F-D-A-P-TR maintains contact resistance below 20 mΩ even after 500 mating cycles, which is critical for high-frequency signal integrity at frequencies above 500 MHz. Gold's low surface resistance minimizes skin-effect losses at GHz-range signal frequencies, ensuring reliable transmission of differential pairs in PCIe, LVDS, or MIPI interfaces routed through the 44-position dual-row socket.
