Frequently Asked Questions
What pitch and position count does SFM-145-T2-S-D-A-K offer for board-to-board connections?
SFM-145-T2-S-D-A-K provides 90 positions in a dual-row layout at 1.27 mm (0.050 inch) pitch, giving designers 45 contacts per row for high-density signal routing on surface mount PCBs with a body length of 2.375 inches.
How does the positioning pin on SFM-145-T2-S-D-A-K improve SMT assembly accuracy?
The integrated positioning pin acts as a mechanical locating feature that registers the connector body into PCB tooling holes, achieving placement accuracy within 0.05 mm and preventing rotational misalignment during 260°C reflow soldering of all 90 surface mount contacts.
In which high-reliability applications is SFM-145-T2-S-D-A-K commonly specified?
SFM-145-T2-S-D-A-K is commonly specified in FPGA mezzanine card interfaces, defense avionics modules, and industrial data acquisition systems where 90 dual-row contacts must maintain signal integrity below 50 mΩ contact resistance over 500+ mating cycles.
Is SFM-145-T2-S-D-A-K compliant with RoHS environmental regulations?
Yes, SFM-145-T2-S-D-A-K is explicitly marked as RoHS compliant (Additional Feature: ROHS COMPLIANT), making it suitable for designs requiring lead-free materials with a body breadth of 0.145 inch and depth of 0.185 inch.
