What are the key features of SFM-145-L2-S-D-LC?
- 90-position dual-row (D) layout on 0.050" (1.27 mm) pitch for ultra-high-density miniaturized PCB interconnect
- Tiger Eye contact technology providing superior retention force and vibration resistance compared to standard spring contacts
- Gold mating surface (30 micro-inches) ensuring low and stable contact resistance across extended mating cycles
- Tin-Nickel termination finish for reliable solder joint formation during reflow SMT assembly
- High-reliability socket strip construction rated for demanding defense, aerospace, and industrial applications
- Square-pin socket contact style compatible with standard 0.050" pitch dual-row header families
What is SFM-145-L2-S-D-LC used for?
SFM-145-L2-S-D-LC is deployed in high-density FPGA expansion modules, rugged defense computing boards, and avionics signal processing cards where 90 positions of Tiger Eye 0.050" pitch dual-row socket connectivity provide vibration-resistant high-reliability mating. The gold-plated contacts and surface mount design also suit high-speed data acquisition systems and medical imaging PCBs requiring consistent low contact resistance across thousands of mating cycles.

Frequently Asked Questions
What contact finish does SFM-145-L2-S-D-LC use, and why does it matter for high-cycle applications?
SFM-145-L2-S-D-LC uses 30 micro-inch gold plating on the mating surface and tin-nickel on the termination, delivering low and stable contact resistance through thousands of mating cycles, which is critical for 90-position test fixtures, field-replaceable modules, and other high-cycle 0.050" pitch dual-row applications.
How does the Tiger Eye contact in SFM-145-L2-S-D-LC improve connector reliability compared to a standard socket contact?
The Tiger Eye contact in SFM-145-L2-S-D-LC uses a multi-point contact geometry that increases normal force on the mating pin compared to standard single-beam sockets, maintaining stable electrical contact under vibration, shock, and thermal cycling across the full 90-position dual-row interface.
What operating temperature range can SFM-145-L2-S-D-LC sustain in avionics and industrial environments?
SAMTEC SFM series Tiger Eye socket strips are rated for -55°C to +125°C operating temperature, making SFM-145-L2-S-D-LC suitable for avionics line-replaceable units, military computing modules, and industrial controllers exposed to extreme thermal swings across 90-pin dual-row signal interfaces.
How does SFM-145-L2-S-D-LC's 0.050" pitch socket compare to 0.100" socket strips for high pin-count board-to-board designs?
At 0.050" (1.27 mm) pitch, SFM-145-L2-S-D-LC routes 90 positions in the same board area that a 0.100" pitch connector would need for only about 45 positions, effectively doubling signal density without increasing connector footprint, which is essential for compact FPGA modules and high-speed data acquisition cards.
