Key Features
- 52-position dual-row terminal layout on a 0.050" (1.27 mm) pitch enabling high-density signal routing within a minimal PCB area
- Tiger Eye contact technology providing gas-tight, low-insertion-force terminations with stable contact resistance over thousands of mating cycles
- Tape-and-reel (TR suffix) packaging for automated SMT pick-and-place assembly, reducing per-unit handling time in high-volume production
Applications
The TFC-126-02-F-D-A-K-TR is suited for multi-channel signal bus applications in FPGA evaluation boards, industrial I/O expansion modules, and embedded computing carriers where 52 signal lines must be routed through a compact dual-row 0.050-inch pitch connector. It is also used in test and measurement backplanes and communications line cards where cost-effective, high-density terminal interconnects reduce BOM cost without sacrificing contact reliability.

Frequently Asked Questions
How many positions does the TFC-126-02-F-D-A-K-TR provide, and in what row configuration?
The TFC-126-02-F-D-A-K-TR is a 52-position, dual-row terminal strip arranged as 2 rows of 26 contacts each, all on a 0.050-inch (1.27 mm) pitch. This high-density layout makes it practical for routing 52 independent signal lines through a board-edge or inline connector in space-constrained PCB designs.
For an FPGA mezzanine card needing 50+ signal connections, how does the TFC-126-02-F-D-A-K-TR compare to a standard 0.100-inch pitch strip?
By using a 0.050-inch (1.27 mm) pitch instead of 0.100-inch (2.54 mm), the TFC-126-02-F-D-A-K-TR fits 52 positions in roughly 1.3 inches of row length, compared to approximately 2.6 inches for an equivalent 0.100-inch pitch strip, effectively halving the board space consumed by the connector and freeing area for routing or components.
What does the F suffix in TFC-126-02-F-D-A-K-TR indicate about its termination style?
The F suffix in SAMTEC part numbering typically designates a compliant-pin or press-fit termination style, allowing the TFC-126-02-F-D-A-K-TR to be pressed into plated through-holes without soldering. This is advantageous in assemblies where selective soldering is impractical or where field replacement of the terminal strip must be possible.
What current and voltage ratings apply to Tiger Eye TFC-series terminal strips like the TFC-126-02-F-D-A-K-TR?
Tiger Eye TFC-series contacts are rated for approximately 1 A per contact at up to 50 V working voltage. For the 52-position TFC-126-02-F-D-A-K-TR, this means each of the 52 signal lines can carry 1 A, making it appropriate for digital bus signals, low-power control lines, and sensor interfaces rather than high-current power distribution.
