What are the key features of SFM-145-02-LM-D-LC?
- 90-position dual-row layout at 0.050" (1.27 mm) pitch delivering very high signal density for compact SMT board-to-board interfaces
- Gold-plated contacts with 2A per pin rating ensuring reliable mating cycle performance in high-reliability connector applications
- Surface mount termination compatible with 260°C peak reflow processes, suitable for automated SMT assembly production lines
What is SFM-145-02-LM-D-LC used for?
The SFM-145-02-LM-D-LC is designed for high-density board-to-board and mezzanine connector applications in data communications switches, FPGA evaluation boards, and server expansion modules that require 90 signals at 0.050" pitch. Its surface mount design integrates directly into automated reflow assembly processes, reducing production complexity for high-volume PCB manufacturing. The wide operating temperature range from -55°C to +125°C makes it equally effective in industrial automation and rugged embedded systems where thermal reliability is critical.

Frequently Asked Questions
How many signals can SFM-145-02-LM-D-LC route in a dual-row layout, and what pitch does it use?
SFM-145-02-LM-D-LC provides 90 contacts arranged in 2 rows at 0.050" (1.27 mm) pitch, with 45 contacts per row. This configuration allows a dense 90-signal interface to occupy a board footprint nearly half the size of an equivalent 0.100" pitch connector, which is critical for high-signal-count designs on compact multi-layer PCBs.
For a 90-pin FPGA daughter card, how does the 2A per pin current rating of SFM-145-02-LM-D-LC support mixed power-signal routing?
With a 2A per pin rating across all 90 contacts, SFM-145-02-LM-D-LC allows designers to dedicate a subset of pins to power delivery—for example, 10 pins at 2A each provide 20A aggregate—while the remaining 80 pins carry differential signals or GPIO. This mixed power-signal configuration is common in FPGA mezzanine cards and high-speed data acquisition modules.
Is SFM-145-02-LM-D-LC suitable for an outdoor industrial control enclosure operating at -40°C or colder?
Yes, SFM-145-02-LM-D-LC is rated for -55°C to +125°C, easily covering the -40°C lower bound required by most industrial temperature specifications. The gold-plated contacts maintain stable contact resistance at low temperatures, making the connector reliable for outdoor PLCs, remote data loggers, and temperature-cycling test fixtures operating in cold environments.
How does SFM-145-02-LM-D-LC differ from SFM-131-L2-L-D-LC-TR in pin count and intended board design?
SFM-145-02-LM-D-LC has 90 positions compared to SFM-131-L2-L-D-LC-TR's 62 positions, both at 0.050" pitch. The 90-pin variant is suited to designs that need a larger signal bus—such as wide memory interfaces or multi-lane high-speed fabric connections—while the 62-pin version is preferred when board space is more limited and fewer than 62 signals are required.
