What are the key features of SFM-148-L2-LM-D-LC?
- 96-position dual-row SMT socket strip with 0.050" (1.27 mm) pitch for high-density board interconnects
- Long-machined contacts (L2 series) provide superior durability and reliable electrical connection over thousands of mating cycles
- Low-profile surface mount design saves vertical board space while maintaining 2 A per pin current capacity
- Compatible with SFM and TSM mating connector families enabling flexible system-level design
What is SFM-148-L2-LM-D-LC used for?
The SFM-148-L2-LM-D-LC is well-suited for high-density board-to-board and mezzanine interconnect applications in embedded computing, telecommunications, and test-and-measurement equipment. Its 96-position dual-row layout at 0.050" pitch allows designers to route 48 differential pairs or up to 96 single-ended signals through a compact footprint. The long-machined contact variant is preferred in applications requiring repeated mating cycles, such as modular server blades and removable I/O cards.

Frequently Asked Questions
How many positions does the SFM-148-L2-LM-D-LC provide and what is its pitch?
The SFM-148-L2-LM-D-LC provides 96 positions arranged in a dual-row configuration with a 0.050" (1.27 mm) pitch. This compact spacing allows up to 96 signal contacts within a small PCB footprint, making it suitable for high-density applications where board space is limited.
What current rating does each pin of the SFM-148-L2-LM-D-LC support?
Each pin in the SFM-148-L2-LM-D-LC is rated for approximately 2 A of current at 25°C. The connector operates reliably within a voltage range up to 250 V AC/DC, making it appropriate for mixed signal and moderate power distribution across its 96 contacts in compact embedded systems.
Which mating connector is compatible with the SFM-148-L2-LM-D-LC for board-to-board stacking?
The SFM-148-L2-LM-D-LC mates with SAMTEC TSM series and SSM series connectors that share the 0.050" pitch dual-row footprint. Using a paired TSM-148 or SSM-148 header, designers can achieve reliable 96-pin board-to-board connections with a typical mating force of under 5 N per pin, suitable for mezzanine and piggyback board stacking assemblies.
Over how many mating cycles is the SFM-148 L2 long-machined contact rated?
The L2 long-machined contact variant of the SFM-148 is rated for a minimum of 100 mating cycles under standard test conditions. The longer contact wipe length improves reliability compared to standard-length contacts, making this part preferable in modular blade servers or hot-swap card designs where connectors are frequently inserted and removed.
