What are the key features of TFM-141-03-SM-D-LC?
- 82-position dual-row (2x41) layout at 1.27 mm pitch offers one of the highest pin counts in the Tiger Eye SMT terminal strip family for extreme-density interconnect designs
- Low-clearance (LC) profile minimizes mating stack height, enabling tightly spaced board-to-board assemblies in constrained enclosures and aerospace packaging
- Tiger Eye gold-plated contact geometry provides consistent mating force distribution and corrosion resistance across thousands of engagement cycles in high-reliability applications
What is TFM-141-03-SM-D-LC used for?
The TFM-141-03-SM-D-LC is engineered for ultra-high-density board-to-board and mezzanine interconnect in aerospace avionics, defense subsystems, and high-performance computing blade architectures. Its 82-position 1.27 mm pitch dual-row low-clearance design permits engineers to consolidate a large number of signal and control lines into a single compact connector pair, reducing overall PCB wiring complexity. The low-clearance profile is especially valued in rack-mount and enclosed-chassis designs where vertical space between mated boards must be minimized.

Frequently Asked Questions
How many positions does the TFM-141-03-SM-D-LC offer, and what does the LC designation indicate?
The TFM-141-03-SM-D-LC provides 82 total positions in a dual-row 2x41 layout at 1.27 mm (0.050 inch) pitch. The LC designation stands for Low Clearance, indicating that the connector is designed with a reduced mated stack height compared to standard Tiger Eye variants, making it ideal for tightly spaced board-to-board assemblies.
For which high-reliability sectors is the TFM-141-03-SM-D-LC's 1 A per-pin rating and gold plating particularly important?
The 1 A per-pin rating combined with gold plating on the TFM-141-03-SM-D-LC makes it critical in aerospace avionics, military electronics, and space-qualified subsystems where signal integrity must be maintained across temperature extremes from -55°C to +125°C and through vibration and shock environments. Gold contacts prevent oxidation and ensure stable contact resistance over the connector's full service life.
How does the TFM-141-03-SM-D-LC compare in pin count to other TFM series connectors for system integration decisions?
At 82 positions, the TFM-141-03-SM-D-LC is one of the highest pin count variants in SAMTEC's TFM surface-mount terminal strip family, which includes options from 4 to over 80 positions at 1.27 mm pitch. Engineers select the 82-position part when consolidating signals from multiple smaller connectors to simplify cable routing and reduce connector counts in complex backplane and mezzanine card designs.
What SMT assembly considerations apply when placing the TFM-141-03-SM-D-LC on a PCB in volume production?
The TFM-141-03-SM-D-LC's 82-position 1.27 mm pitch dual-row footprint requires precise stencil printing and reflow profile management to ensure uniform solder paste coverage across all 82 contacts. Paste stencil apertures should match the 1.27 mm grid, and reflow profiles should target a peak temperature of approximately 245°C to achieve reliable solder joints without damaging the low-clearance connector body or adjacent SMT components.
