Frequently Asked Questions
How many positions and what pitch does the TFC-125-02-FM-D-A-K offer for board connector applications?
The TFC-125-02-FM-D-A-K provides 50 positions in a dual-row layout with 0.050 inch (1.27 mm) pitch. This configuration delivers 25 pins per row, enabling a high pin count within a body length of 1.375 inches, which is suitable for dense signal routing on compact PCBs.
What contact finish specification does the TFC-125-02-FM-D-A-K use and how does it affect mating reliability?
The mating contacts on the TFC-125-02-FM-D-A-K are finished with gold (3 µin) over phosphor bronze. Gold plating provides corrosion resistance and consistent low contact resistance across the 50 mating positions, ensuring reliable signal integrity in commercial and industrial electronics over extended service life.
How does the TFC-125-02-FM-D-A-K board mounting option help during PCB assembly?
The TFC-125-02-FM-D-A-K includes a peg board mounting option that locks the connector body to the PCB during soldering. This mechanical feature prevents connector movement and misalignment during reflow or wave soldering at temperatures up to 260°C, improving assembly yield in automated production environments.
Is the TFC-125-02-FM-D-A-K an appropriate alternative in cost-sensitive high-volume designs?
Yes, the Tiger Eye cost-effective design of the TFC-125-02-FM-D-A-K makes it a strong candidate for high-volume PCB assemblies where budget constraints are a factor. With 50 positions at 0.050 inch pitch, it maintains functional density comparable to premium connectors while offering a more economical price point for commercial applications.
