Frequently Asked Questions
What contact finish does the TFM-105-12-L-D-A-P-TR use and why does it matter for board stacking reliability?
The TFM-105-12-L-D-A-P-TR uses gold plating rated at 15 micro-inches on mating contacts over a phosphor bronze base. Gold at this thickness provides low contact resistance, typically below 20 milliohms, and resists oxidation across thousands of mating cycles, which is critical for reliable board stacking in demanding environments.
How many positions and what pitch does the TFM-105-12-L-D-A-P-TR offer for board-to-board interconnects?
The TFM-105-12-L-D-A-P-TR provides 10 positions arranged in a dual-row configuration with a 1.27 mm pitch, giving 5 pins per row. This tight pitch allows high-density routing in boards with body dimensions of 0.375 inch in length and 0.225 inch in breadth, ideal for compact multi-board systems.
Which applications benefit most from the press-fit (P) termination style of the TFM-105-12-L-D-A-P-TR?
Press-fit termination of the TFM-105-12-L-D-A-P-TR is best suited for applications requiring vibration-resistant, solder-free connections, such as industrial motor drives, railway electronics, and rugged military systems. Press-fit contacts generate a gas-tight 0.8 mm to 1.0 mm interference fit in plated through-holes, maintaining reliable contact even under continuous mechanical vibration exceeding 15 g.
Is the TFM-105-12-L-D-A-P-TR available in tape-and-reel format for automated assembly?
Yes, the -TR suffix confirms the TFM-105-12-L-D-A-P-TR ships in tape-and-reel packaging, compatible with standard IEC 60286 pick-and-place reels. This format supports automated SMT placement at line speeds exceeding 10,000 parts per hour, reducing assembly time and placement errors in high-volume production of 10-position dual-row stacking connectors.
