Frequently Asked Questions
What is the pin pitch and position count of the TFC-123-02-F-D-A-K?
The TFC-123-02-F-D-A-K is a 46-position dual-row terminal strip with 0.050-inch (1.27 mm) pitch, offering a high-density signal interconnect solution in a compact through-hole footprint. This pitch supports routing up to 46 signals in approximately 23 mm of board length.
How does the Tiger Eye contact design in the TFC-123-02-F-D-A-K improve connection reliability over standard bifurcated contacts?
The Tiger Eye contact design provides a wiping action during mating that displaces surface oxides and contaminants, achieving contact resistance below 20 milliohms. Unlike simple stamped bifurcated contacts, the Tiger Eye geometry maintains consistent normal force across the mating pin diameter range of 0.025 inch to 0.030 inch, ensuring reliable connections through thousands of insertion cycles in test and measurement applications.
For which board-to-board or cable-to-board applications is the TFC-123-02-F-D-A-K best suited?
The TFC-123-02-F-D-A-K is best suited for dense board-to-board mezzanine connections and wire-to-board harness terminations in high-channel-count data acquisition systems, FPGA daughter cards, and test fixture boards. Its 0.050-inch pitch handles 46 signals in a space that would require a 0.100-inch connector twice as long, supporting 3.3 V to 5 V digital signal routing in compact embedded systems.
What current rating per contact does the TFC-123-02-F-D-A-K support, and can it handle mixed signal and power pins?
SAMTEC TFC series contacts are rated for approximately 1 A per pin at 0.050-inch pitch, suitable for signal lines and low-current power rails up to 1 A each. For higher power distribution requirements, adjacent pins can be paralleled to carry up to 2 A or 3 A per combined contact pair, which is a common practice in FPGA core voltage supply rails routed through 1.27 mm pitch connectors.
