What are the key features of SFM-145-L2-L-D-LC?
- 90-position dual-row layout on 0.050" (1.27 mm) pitch maximizes signal density in compact board-to-board designs
- Split board lock mounting option provides mechanical retention to withstand vibration and shock in harsh environments
- Matte tin over nickel contact finish on both mating and termination surfaces ensures reliable electrical contact over thousands of cycles
- RoHS-compliant construction meets global environmental and regulatory standards for lead-free manufacturing
What is SFM-145-L2-L-D-LC used for?
The SFM-145-L2-L-D-LC is used in high-pin-count mezzanine and daughterboard interconnects for servers, industrial controllers, and rack-mounted test systems. Its 90-position dual-row layout on a 0.050-inch pitch packs 90 signal or power contacts into a 2.405-inch body length, supporting complex backplane routing in compact enclosures. The split board lock feature makes it especially suited for applications exposed to vibration, such as ruggedized military electronics and automotive infotainment modules.

Frequently Asked Questions
How many positions does the SFM-145-L2-L-D-LC provide, and what is the body length?
The SFM-145-L2-L-D-LC provides 90 positions in a dual-row configuration, with a body length of 2.405 inches (approximately 61 mm) on a 0.050-inch (1.27 mm) pitch. This high-contact-count format is suitable for data buses, high-speed signal routing, and mixed power-and-signal mezzanine connections in servers and industrial compute platforms.
What mechanical retention mechanism does the SFM-145-L2-L-D-LC use, and why does it matter for ruggedized designs?
The SFM-145-L2-L-D-LC uses a split board lock feature, which extends through the PCB and snaps into place to resist axial pull-out forces. This mechanical retention is critical in vibration-prone environments such as military electronics or automotive systems, where a connector lacking a board lock can work loose over thousands of vibration cycles and cause intermittent failures.
What contact finish does the SFM-145-L2-L-D-LC use, and how does it affect mating cycle life?
The SFM-145-L2-L-D-LC uses a matte tin finish over a nickel barrier on both the mating and termination surfaces. Matte tin provides good solderability and corrosion resistance, typically supporting 30 or more mating cycles. The nickel underplate acts as a diffusion barrier that prevents tin whisker growth and maintains contact integrity at elevated temperatures up to 85°C in most operating environments.
Which SAMTEC mating headers pair with the SFM-145-L2-L-D-LC for stacking board assemblies?
The SFM-145-L2-L-D-LC mates with SAMTEC TFM and TSM series headers sharing the same 0.050-inch (1.27 mm) pitch and dual-row footprint. Available stacking heights range from approximately 2 mm to 20 mm, letting engineers select board separation based on component height clearance or airflow requirements in blade server and mezzanine module designs.
