What are the key features of SFM-145-T2-FM-D-A-P?
- 90-position dual-row configuration at 1.27 mm (0.050 inch) pitch enabling extremely high contact density within minimal PCB area
- High-reliability socket strip design with gold-plated contacts ensuring low contact resistance and extended mating cycle life
- Anti-wicking (A) terminal option preventing solder from contaminating the contact area during SMT reflow
- Surface mount footprint compatible with automated pick-and-place and reflow soldering for high-volume PCB manufacturing
What is SFM-145-T2-FM-D-A-P used for?
The SFM-145-T2-FM-D-A-P is deployed in high-reliability applications such as aerospace avionics, medical instrumentation, and defense electronics where 90-position fine-pitch socket connectivity must endure harsh environments. Its 1.27 mm pitch dual-row surface mount format supports dense mezzanine board-to-board connections and module daughter card interfaces. The anti-wicking terminal feature ensures solder joint integrity during automated SMT assembly.

Frequently Asked Questions
What makes the 1.27 mm pitch of SFM-145-T2-FM-D-A-P advantageous over standard 2.54 mm pitch alternatives?
The 1.27 mm (0.050 inch) pitch of SFM-145-T2-FM-D-A-P achieves twice the contact density compared to 2.54 mm pitch connectors, allowing 90 positions in roughly half the board space. This is critical for high-density mezzanine card designs, avionics modules, and miniaturized industrial controllers where PCB real estate is severely constrained and signal count requirements exceed 64 pins.
What does the anti-wicking (A) suffix mean for SFM-145-T2-FM-D-A-P, and when is this feature critical?
The 'A' suffix indicates anti-wicking terminals that prevent molten solder from traveling up the contact during reflow soldering. This protects the mating contact zone from contamination, maintaining reliable electrical connection across all 90 positions. Anti-wicking is especially critical in high-reliability sectors such as aerospace, defense, and medical where contact integrity must be guaranteed over thousands of mating cycles at temperatures from -55°C to +125°C.
For a high-density mezzanine design, how many signal lines can be routed through a single SFM-145-T2-FM-D-A-P connector?
A single SFM-145-T2-FM-D-A-P provides 90 total contact positions in a dual-row 1.27 mm pitch surface mount footprint, enabling designers to route up to 80 signal lines plus dedicated power and ground pins through one connector. This consolidation is ideal for 64-bit data bus designs with control, clock, and power signals, reducing the board interconnect count while maintaining signal integrity at high-speed logic levels of 1.8 V, 2.5 V, or 3.3 V.
Is the SFM-145-T2-FM-D-A-P a stocked part available for fast delivery, and what is the recommended mating connector?
The SFM-145-T2-FM-D-A-P is carried by major distributors including Digi-Key and Mouser and is typically available for same-day or next-day dispatch with worldwide shipping. It mates with SAMTEC's TSM or TFM series 1.27 mm pitch dual-row headers, which are specified to achieve contact resistance below 20 milliohms and are rated for a minimum of 30 mating cycles in high-reliability socket strip configurations.
