SFM-139-T2-H-D-A SAMTEC Connector (Other) In Stock

What are the key features of SFM-139-T2-H-D-A?

• 78-position dual-row socket at 1.27 mm pitch packs 39 contacts per row for high-density SMT mezzanine interconnects
• High-retention (H) contact design provides increased mating force for secure retention in high-vibration environments without secondary locking hardware
• Gold-over-nickel contact plating maintains contact resistance below 20 mΩ across hundreds of mating and un-mating cycles
• Rated 2 A per pin continuous with an operating temperature range of -55 °C to +125 °C, meeting industrial and mil-grade reliability requirements
• SMT termination style integrates into standard lead-free reflow assembly processes up to 260 °C peak reflow temperature

What is SFM-139-T2-H-D-A used for?

The SFM-139-T2-H-D-A is applied in board-to-board interconnects on FPGA evaluation modules, embedded processor carrier cards, and industrial control mezzanine assemblies requiring 78 circuits at a compact 1.27 mm pitch. The high-retention contact variant is especially valued in ruggedized field equipment—such as transportation electronics and industrial robots—where vibration would otherwise cause intermittent contact with standard-retention socket strips. Defense and avionics board-stack designers also select this series for its extended temperature rating and compatibility with the SAMTEC TSM header ecosystem.
