What are the key features of TFM-141-04-SM-D-LC?
- Tiger Eye dual-beam SMT contacts on 0.050" (1.27 mm) pitch deliver stable low contact resistance across hundreds of mating cycles in high-speed board-to-board applications
- Board-lock (LC) retention anchors the 82-position dual-row connector to the PCB via press-fit posts, protecting solder joints from vibration and repeated mating forces
- Surface-mount termination eliminates through-hole drilling, simplifying PCB fabrication and enabling single-side assembly in space-constrained compact module designs
What is TFM-141-04-SM-D-LC used for?
The TFM-141-04-SM-D-LC is suited for high-density mezzanine interconnections in FPGA daughter boards, telecommunications line cards, and high-channel-count data acquisition systems where 82 signals must be routed through a minimal PCB footprint. The surface-mount configuration with board-lock retention supports fully automated reflow assembly while providing the mechanical robustness needed for rack-mounted or portable instruments subject to vibration. Its 0.050" pitch makes it an efficient alternative to 0.100" solutions when PCB real estate is limited.

Frequently Asked Questions
How many differential signal pairs can TFM-141-04-SM-D-LC support in an FPGA mezzanine board application?
With 82 positions arranged in 2 rows on 0.050" (1.27 mm) pitch, the TFM-141-04-SM-D-LC can accommodate up to 41 differential signal pairs if all contacts are dedicated to differential signaling. In a practical FPGA mezzanine layout, a typical allocation might be 32 differential pairs for high-speed lanes plus power, ground, and control signals, making it suitable for multi-gigabit serial interfaces and parallel buses.
Why does the surface-mount termination of TFM-141-04-SM-D-LC simplify PCB manufacturing compared to through-hole alternatives?
Surface-mount termination eliminates the need to drill plated through-holes for each of the 82 pins, reducing PCB layer stackup constraints and fabrication cost. The SMT pads on 0.050" pitch can be placed on a single board side, freeing the opposite side for additional routing or components. Reflow soldering of the TFM-141-04-SM-D-LC is compatible with standard lead-free solder profiles, simplifying process control on automated assembly lines.
When sourcing TFM-141-04-SM-D-LC for a new product introduction, what lead time and packaging options should procurement expect?
SAMTEC Tiger Eye terminal strips such as the TFM-141-04-SM-D-LC are typically available with lead times ranging from 2 to 8 weeks depending on order quantity. The connector is available in tape-and-reel or cut-strip packaging to match both automated pick-and-place assembly and prototype builds. For production volumes of the 82-position, 0.050" pitch dual-row part, requesting factory stock or blanket orders at least 6 weeks ahead of the build date reduces schedule risk.
