What are the key features of SFM-145-L2-F-D-A-K?
- 90-position dual-row layout at 0.050" (1.27 mm) pitch delivers extreme contact density for compact mezzanine and module interconnect
- High-reliability gold-plated contacts rated for thousands of insertion cycles maintain stable low-resistance connections over device lifetime
- SMT footprint compatible with standard reflow soldering enables flat board profile in space-constrained mezzanine card stacking assemblies
What is SFM-145-L2-F-D-A-K used for?
The SFM-145-L2-F-D-A-K is designed for high-density mezzanine card and module stacking applications in military electronics, medical instrumentation, and high-performance computing where 90 positions at 0.050 inch pitch minimize board space usage. Its high-reliability rating suits avionics, satellite, and mission-critical embedded systems demanding connectors that maintain electrical integrity across extreme temperatures and vibration. The SMT format enables thin board stack profiles in portable diagnostic equipment and rack-mount server modules.

Frequently Asked Questions
How does the 0.050 inch pitch of SFM-145-L2-F-D-A-K compare to standard 0.100 inch pitch socket strips?
The SFM-145-L2-F-D-A-K at 0.050 inch (1.27 mm) pitch packs 90 positions into approximately half the board length of an equivalent 0.100 inch pitch connector with the same position count. This doubled contact density per unit length is essential for mezzanine card interconnects in compact military avionics and medical device boards where every square millimeter of PCB area is constrained.
For which high-reliability application domains is SFM-145-L2-F-D-A-K specifically qualified?
The SFM-145-L2-F-D-A-K high-reliability socket strip is designed for demanding applications including military avionics, satellite electronics, medical imaging, and high-performance computing mezzanine boards. Its gold-plated contacts support thousands of mating cycles, and the 90-position dual-row SMT configuration provides the connection density needed for complex signal and power routing in mission-critical embedded systems.
What is the mating header series compatible with SFM-145-L2-F-D-A-K for board-to-board stacking?
The SFM-145-L2-F-D-A-K mates with SAMTEC's SFM-series header strips that share the same 0.050 inch pitch and 90-position dual-row footprint. The matched mating pair provides a fully characterized insertion force and contact resistance specification, ensuring a reliable 90-contact board-to-board interconnect suitable for high-vibration and high-cycle-count environments in industrial and aerospace equipment.
