Frequently Asked Questions
What contact finish does the TFC-105-02-LM-D-A-K-TR use on its mating contacts, and why does it matter?
The TFC-105-02-LM-D-A-K-TR uses gold (15 µin) plating on the mating contact surfaces, applied over phosphor bronze contact material. Gold plating provides low and stable contact resistance across the rated mating cycles, resisting oxidation and corrosion for reliable signal integrity in embedded and industrial PCB interconnect applications.
How does the tape-and-reel packaging of the TFC-105-02-LM-D-A-K-TR benefit automated assembly?
The TR (tape-and-reel) suffix indicates this connector is packaged for automated pick-and-place equipment. Tape-and-reel eliminates manual feeder loading, supporting high-throughput SMT production lines. This is especially beneficial for high-volume runs where thousands of 10-position connectors must be placed accurately at 1.27 mm pitch on compact PCBs.
For a compact industrial control board, what board space does the TFC-105-02-LM-D-A-K-TR occupy?
The TFC-105-02-LM-D-A-K-TR has a body length of 0.375 inch, breadth of 0.225 inch, and depth of 0.226 inch. This compact footprint at 0.050" (1.27 mm) pitch allows designers to route 10 dual-row signals in a very small PCB area, making it appropriate for space-constrained industrial control and instrumentation boards.
When is TFC-105-02-LM-D-A-K-TR a cost-effective alternative to premium fine-pitch connectors with higher gold plating?
The TFC-105-02-LM-D-A-K-TR is the preferred choice when 15 µin gold plating provides sufficient contact reliability for the target mating cycle count and environment, avoiding the cost premium of heavier gold deposits (e.g., 30 µin or 50 µin). For high-volume consumer or industrial applications requiring a 10-pin dual-row 1.27 mm pitch connector with moderate cycle life, this part delivers the best cost-to-performance ratio.
