Key Features
- Tiger Eye 1.27 mm pitch dual-row board stacking terminal strip with 250 positions for ultra-high density interconnect
- Shrouded housing with polarization key prevents misinsertion and provides additional mechanical retention during mating
- Gold flash over nickel contact finish on phosphor bronze contacts for low-resistance, cost-effective signal transmission
Applications
The TFC-125-12-F-D-A is suited for high-density board-to-board stacking applications in embedded computing modules, FPGA development platforms, and military-grade backplane systems that demand reliable 1.27 mm pitch connectivity. The Tiger Eye shrouded design ensures secure polarized mating in vibration-prone environments such as industrial machinery and avionics chassis. Its standard through-hole tail with gold flash contacts facilitates integration into both standard and ruggedized PCB assemblies.

Frequently Asked Questions
How many positions does the TFC-125-12-F-D-A provide and what pitch does it use?
The TFC-125-12-F-D-A is a 250-position dual-row connector using a 1.27 mm (0.050 inch) pitch, enabling extremely high contact density within a body length of 2.625 inches and body breadth of 0.225 inches on the PCB.
What makes the Tiger Eye shrouded design beneficial for vibration-prone environments?
The Tiger Eye shrouded housing mechanically polarizes mating connectors and adds retention force beyond simple contact friction, keeping mated connectors securely together even under shock and vibration conditions up to the levels seen in industrial and avionic-grade equipment, where unmated connectors could cause system failure.
What contact materials and finishes are used in the TFC-125-12-F-D-A?
The TFC-125-12-F-D-A uses phosphor bronze contacts with a gold flash over nickel mating surface finish, providing a balance of cost efficiency and low contact resistance, rated for reliable signal transmission across 50 micro-inches of gold plating on the mating zone.
When is TFC-125-12-F-D-A a better choice than a standard non-shrouded terminal strip?
Whenever connector misinsertion or unmating under vibration is a concern—for example in board-stacking mezzanine systems inside industrial controllers or defense electronics—the TFC-125-12-F-D-A's shrouded 1.27 mm Tiger Eye housing provides polarization and mechanical retention that bare unshrouded strips at the same 1.27 mm pitch cannot match.
