Frequently Asked Questions
What is the Tiger Eye contact design in the TFC-126-02-F-D-A-K, and how does it improve reliability?
The Tiger Eye contact is a proprietary Samtec design that uses a dual-beam wiping geometry to ensure consistent low-resistance mating. During engagement, each contact wipes across the mating surface, removing oxide layers and achieving contact resistance well below 20 mΩ. This design supports reliable performance over hundreds of mating cycles, making the TFC-126-02-F-D-A-K suitable for high-reliability 52-position board-to-board interconnect.
How many positions does the TFC-126-02-F-D-A-K provide, and at what pitch?
The TFC-126-02-F-D-A-K provides 52 positions arranged in a dual-row configuration at 0.050-inch (1.27 mm) pitch. This gives 26 contacts per row, supporting high signal density in board-to-board mezzanine applications where compact PCB real estate is a critical constraint.
When should a designer choose the TFC-126-02-F-D-A-K over a standard Samtec terminal strip?
The TFC-126-02-F-D-A-K is the preferred choice when cost reduction is a priority but the application still requires a reliable 52-position dual-row connection at 0.050-inch pitch. Its cost-effective construction lowers BOM cost compared to premium Samtec series while retaining the Tiger Eye contact that provides low contact resistance under 20 mΩ and multi-hundred cycle mating life, ideal for commercial telecom and computing products.
Is the TFC-126-02-F-D-A-K compatible with standard SMT assembly processes?
Yes. The TFC-126-02-F-D-A-K uses surface mount termination compatible with standard automated SMT pick-and-place and lead-free reflow soldering processes. With a 0.050-inch pitch and 52-position dual-row layout, it fits within established SMT design rules and can be soldered at reflow temperatures up to 260 °C, supporting high-volume PCB production in industrial and commercial applications.
