What are the key features of TFC-145-02-F-D-A-K?
- 90-position dual-row Tiger Eye terminal strip on 1.27mm (0.050") pitch delivering high signal density in a compact board connector footprint
- Floating mount (F) design compensating for PCB misalignment during mating, reducing mechanical stress on solder joints in stacked board assemblies
- Cost-effective Tiger Eye contact geometry providing reliable spring force and low-insertion-force mating over thousands of connect/disconnect cycles
What is TFC-145-02-F-D-A-K used for?
TFC-145-02-F-D-A-K is used in board-to-board stacking applications where 90 signal positions must be routed between two PCBs at 1.27 mm pitch with alignment tolerance compensation. Its floating mount design makes it suitable for industrial backplanes, embedded computing modules, and high-density data acquisition cards where rigid press-fit or fixed mounting would induce unacceptable PCB warpage stress. The compact 0.050 inch pitch supports high pin count interfaces in space-constrained rack-mount and embedded systems.

Frequently Asked Questions
How many signal positions does TFC-145-02-F-D-A-K provide and at what pitch?
TFC-145-02-F-D-A-K provides 90 contact positions arranged in a dual-row configuration on a 1.27 mm (0.050 inch) pitch. This high pin count on a fine pitch allows routing of 45 differential pairs or up to 90 single-ended signals through a single connector, making it highly efficient for FPGA I/O expansion and high-density module interfaces.
What alignment benefit does the floating mount design of TFC-145-02-F-D-A-K provide in stacked board assemblies?
The floating mount (F suffix) allows lateral movement of up to ±0.5 mm between the connector body and the PCB footprint, compensating for manufacturing tolerances when two boards are mated. This prevents the 90 solder joints from experiencing shear stress due to board-to-board misalignment, significantly improving long-term joint reliability in vibrating or thermally cycling environments operating from -40°C to +85°C.
When is TFC-145-02-F-D-A-K a more suitable choice than a 90-position FFC/FPC cable assembly?
TFC-145-02-F-D-A-K is preferable to a 90-position FFC/FPC cable when the two boards are stacked in close proximity without requiring flexible routing, and when direct board-to-board impedance continuity at 1.27 mm pitch is needed. The rigid terminal strip eliminates cable delay and impedance discontinuities, supporting signal integrity for data rates up to several hundred MHz, whereas FFC cables introduce additional capacitance per 10 mm of length that degrades high-speed signal quality.
