Frequently Asked Questions
What pitch and row configuration does the SFM-144-02-SM-D-A use, and how does that affect PCB density?
The SFM-144-02-SM-D-A uses a 0.050" (1.27 mm) pitch dual-row layout with 144 positions total. This fine pitch allows designers to route 144 signal lines within a compact footprint, significantly reducing board area compared to 0.100" pitch alternatives, making it ideal for high-density PCB designs where space is at a premium.
In which application environments is the SFM-144-02-SM-D-A best suited, and what reliability level does it support?
This connector is well suited for communications infrastructure, test and measurement systems, and industrial control equipment requiring high-reliability interconnects. The SFM series is rated for multiple mating cycles and designed to maintain signal integrity across 144 dual-row contacts under vibration and thermal cycling conditions encountered in harsh environments.
How does the SMT termination style of SFM-144-02-SM-D-A benefit automated manufacturing?
The surface-mount termination style allows the SFM-144-02-SM-D-A to be placed by pick-and-place equipment and soldered in a standard reflow oven alongside other SMT components. This eliminates hand-soldering of 144 pins, reduces assembly time, improves solder joint consistency, and supports high-volume PCB production runs with lower per-unit labor cost.
