Frequently Asked Questions
How many contacts does the SFM-145-T2-LM-D-A-P provide, and what pitch does it use?
The SFM-145-T2-LM-D-A-P provides 90 contacts in a dual-row layout with 0.050" (1.27 mm) pitch, giving 45 positions per row, enabling high-density signal routing within a compact PCB footprint for embedded and mezzanine board applications.
What does the low-mount (LM) designation mean for the SFM-145-T2-LM-D-A-P, and which stacking height does it suit?
The LM (low-mount) designation indicates a reduced mating height, typically under 4 mm above the PCB surface, making the SFM-145-T2-LM-D-A-P suitable for slim card assemblies or enclosures where vertical clearance is limited to a few millimeters.
What are the most common system-level applications for the SFM-145-T2-LM-D-A-P in industrial or aerospace designs?
This socket strip is commonly used in aerospace avionics daughter cards, industrial FPGA mezzanine modules, and high-cycle test fixture boards, where a 90-pin 0.050" pitch low-profile connector must handle operating temperatures from -55°C to +125°C reliably.
Is the SFM-145-T2-LM-D-A-P compatible with RoHS and lead-free manufacturing requirements?
Yes, the SFM-145-T2-LM-D-A-P is RoHS compliant and is manufactured with lead-free materials compatible with standard reflow soldering profiles, allowing integration into modern eco-compliant PCB assembly processes without sacrificing the connector's high-reliability performance.
