Frequently Asked Questions
What is the mating contact finish specification of the TFM-145-12-S-D, and why does it matter for signal integrity?
The TFM-145-12-S-D uses 30 µin gold plating over 50 µin nickel on mating contacts, delivering low and stable contact resistance below 20 mΩ. This finish prevents oxidation and corrosion, maintaining reliable signal integrity across thousands of mating cycles in demanding environments.
How many signal positions can the TFM-145-12-S-D accommodate, and what is its center-to-center pitch?
The TFM-145-12-S-D provides 45 positions per row in a dual-row configuration, totaling 90 contacts on a 0.050" (1.27 mm) pitch. The body length is 2.375 inches, making it a compact yet high-density solution for board-to-board signal routing applications.
In which high-reliability system designs is the TFM-145-12-S-D Tiger Eye terminal strip most commonly used?
This Tiger Eye receptacle is widely used in telecommunications line cards, industrial control backplanes, and defense electronics where 90 signals must be routed in a 2.375-inch footprint. The shrouded ELP body and gold contacts support operating temperatures across a wide range, typically -55°C to +125°C, ensuring reliable performance in harsh environments.
