What are the key features of TFM-125-12-S-D-LC?
- 50-position dual-row Tiger Eye terminal strip on 0.050-inch (1.27 mm) pitch for high-density surface-mount designs
- Matte tin over nickel contact finish provides reliable, low-resistance mating with standard PCB pads
- Split board lock mounting option ensures mechanical retention and prevents connector movement during mating
- Vertical SMT orientation minimizes board height while maintaining full-density signal routing
What is TFM-125-12-S-D-LC used for?
The TFM-125-12-S-D-LC is well suited for high-density board-to-board interconnect applications in industrial automation, telecommunications, and embedded computing systems. Its 50-position dual-row layout on a 0.050-inch pitch accommodates parallel signal buses and power distribution in compact PCB assemblies. The Tiger Eye contact technology also makes it a reliable choice for test and measurement interfaces requiring consistent electrical performance across many mating cycles.

Frequently Asked Questions
What contact finish does the TFM-125-12-S-D-LC use and why does it matter?
The TFM-125-12-S-D-LC uses a matte tin over nickel contact finish, which provides good corrosion resistance and reliable electrical conductivity. This finish is compatible with standard solder and press-fit processes and supports stable contact resistance across temperatures ranging from -55°C to +125°C.
How does the split board lock feature benefit PCB assembly with the TFM-125-12-S-D-LC?
The split board lock mounting option on the TFM-125-12-S-D-LC mechanically anchors the connector body to the PCB, preventing lateral movement and improving resistance to shock and vibration. This is especially valuable in industrial or ruggedized applications where connectors may experience forces exceeding 10 G.
For a 50-position signal interface at 0.050-inch pitch, how does this connector compare to 0.100-inch pitch alternatives?
The TFM-125-12-S-D-LC at 0.050-inch (1.27 mm) pitch accommodates 50 positions in approximately the same board footprint that a 0.100-inch pitch connector would need for only 25 positions, effectively doubling the connection density. This makes the TFM-125-12-S-D-LC ideal when board space is limited and signal count must remain high.
What industries typically use the TFM-125-12-S-D-LC in production designs?
The TFM-125-12-S-D-LC sees use in telecommunications line cards, industrial PLC backplanes, and embedded computing daughterboards. Its 50-position, 0.050-inch pitch SMT format suits high-channel-count data acquisition systems and control boards operating in environments up to +125°C.
