Frequently Asked Questions
How does the STL tail of the SFM-123-02-STL-D-A-P-TR differ from a standard LC tail, and which applications benefit?
The STL tail on the SFM-123-02-STL-D-A-P-TR provides a longer solderable lead than the standard LC tail, increasing the solder fillet height on the PCB pad by approximately 0.5 mm to 1 mm. This added solder contact area improves mechanical pull strength on the 46-pin connector, benefiting applications subject to vibration or frequent mating forces such as field instruments and avionics modules.
What signal integrity characteristics make the SFM-123-02-STL-D-A-P-TR suitable for high-speed parallel buses?
The SFM-123-02-STL-D-A-P-TR supports high-speed signaling with contact resistance below 20 milliohms and rated insulation resistance above 1000 MΩ at 100 V DC. At 0.050" pitch with 46 positions, adjacent-pin crosstalk is minimized by the tight dual-row geometry, enabling reliable parallel bus operation at signal frequencies up to 500 MHz in compact PCB designs.
For a 46-pin expansion interface on a ruggedized module, when is SFM-123-02-STL-D-A-P-TR a stronger choice than a board-to-wire cable assembly?
The SFM-123-02-STL-D-A-P-TR eliminates cable routing complexity by providing a direct board-to-board interface with 46 positions at 0.050" pitch, reducing assembly time compared to individual wire terminations. Its surface mount STL tail achieves solder joint pull strength exceeding 5 N per pin, offering better vibration resistance than typical crimped wire-to-board connectors in ruggedized enclosures.
