What are the key features of SFM-148-L2-FM-D-A-K?
- 96 positions in a dual-row 1.27mm pitch surface mount layout achieves extremely high pin density for high-speed mezzanine and module-on-carrier board stacking applications
- High-reliability machined contacts with gold-over-nickel finish rated for 500+ mating cycles ensure long-term signal integrity for differential pairs and high-speed serial interfaces
- SMT termination with precision-machined socket housing provides tight coplanarity control, ensuring uniform solder joint quality across all 96 positions during reflow assembly
What is SFM-148-L2-FM-D-A-K used for?
The SFM-148-L2-FM-D-A-K is used in high-density mezzanine interconnect applications such as FPGA mezzanine card (FMC) sockets, COM Express carrier boards, and high-speed data acquisition modules where 96 pins at 1.27mm pitch are needed for differential signal routing. Its high-reliability machined contact design makes it suitable for mil-aero, medical imaging, and industrial computing systems that demand consistent signal integrity over thousands of operational hours. The surface mount format also supports automated PCB assembly in high-volume production of telecom and networking line cards.

Frequently Asked Questions
What is the pin pitch and position count of the SFM-148-L2-FM-D-A-K, and what board stacking formats does it support?
The SFM-148-L2-FM-D-A-K has 96 positions arranged in a dual-row layout on a 1.27mm (0.050 inch) pitch. This configuration is compatible with high-density mezzanine standards including FMC (FPGA Mezzanine Card) and similar module-on-carrier architectures used in FPGA development, radar, and data acquisition systems.
How does the machined contact design of the SFM-148-L2-FM-D-A-K improve high-speed signal performance compared to stamped contacts?
Machined contacts in the SFM-148-L2-FM-D-A-K provide tighter dimensional tolerances and more consistent contact geometry than stamped contacts, resulting in lower and more predictable insertion loss and impedance discontinuities at frequencies above 1GHz. This makes the connector suitable for high-speed differential interfaces such as PCIe, LVDS, and SERDES links running at multiple Gbps.
What mating cycle durability does the SFM-148-L2-FM-D-A-K support, and for which environments is it rated?
The SFM-148-L2-FM-D-A-K is rated for 500 or more mating cycles with gold-over-nickel plating on the contact mating surfaces. The high-reliability construction suits industrial, military, and aerospace environments with wide temperature ranges, mechanical shock, and vibration exposure where connector failure would be costly to repair.
Is the SFM-148-L2-FM-D-A-K compatible with standard SMT reflow assembly, and what coplanarity does it maintain?
Yes, the SFM-148-L2-FM-D-A-K is designed for surface mount reflow soldering. SAMTEC's precision machined housing maintains coplanarity of 0.10mm or better across all 96 termination pins, ensuring uniform solder paste coverage and reliable joint formation during standard lead-free reflow profiles without requiring hand soldering or rework.
