Frequently Asked Questions
How many positions does TFC-109-02-L-D-A have and what pitch does it use?
The TFC-109-02-L-D-A is an 18-position terminal strip arranged in 2 rows at 0.050 inch (1.27 mm) pitch. This high-density layout accommodates 18 signal connections in roughly the same PCB footprint as a 9-position 0.100 inch connector, supporting miniaturization in embedded and portable board designs.
What makes the Tiger Eye contact design of TFC-109-02-L-D-A advantageous for industrial cable assemblies?
The Tiger Eye contact geometry in the TFC-109-02-L-D-A provides a wiping action as the mating connector is inserted, clearing surface oxidation from the tin-over-nickel contacts. This results in lower contact resistance and more reliable interconnect in environments with temperature cycling or mild corrosion exposure typical of industrial I/O panels.
Is TFC-109-02-L-D-A suitable for applications that require MIL or IEC connector certification?
No, the TFC-109-02-L-D-A does not conform to MIL, IEC, or DIN standards. It is a commercial-grade, cost-effective 18-position 0.050 inch pitch terminal strip designed for consumer electronics, embedded computing, and light industrial boards where standard certifications are not required and minimizing connector cost in high-volume production is the priority.
What contact finish does TFC-109-02-L-D-A use and how does the nickel barrier affect soldering?
The termination contacts use tin over a nickel barrier finish, which improves wettability during wave or reflow soldering while the nickel layer prevents tin diffusion into the copper substrate. This maintains joint integrity over 1000-hour aging cycles and prevents intermetallic growth that could increase termination resistance in 0.050 inch pitch solder joints.
