Frequently Asked Questions
How many positions and what pitch does the TFC-145-02-F-D-A provide for board stacking?
The TFC-145-02-F-D-A is a 90-position dual-row male connector on a 0.100 inch (2.54 mm) pitch, giving a total of 90 signals in a compact 4.625 inch body length. This layout supports high-density inter-board wiring in mezzanine and backplane card assemblies while maintaining a standard pitch compatible with common PCB layout rules.
What contact finish is used on the TFC-145-02-F-D-A mating interface, and how does that affect connector lifespan?
The mating contacts use gold flash over nickel, which provides low contact resistance typically below 20 milliohms and protects against oxidation. Gold flash is rated for moderate mating cycles, generally 25 to 50 cycles in SAMTEC specifications, making the connector well suited for daughtercard modules that are installed once or infrequently replaced during system maintenance.
Which industrial or computing applications typically use the TFC-145-02-F-D-A shrouded board stacking connector?
This connector suits server mezzanine cards, embedded computing modules, industrial programmable logic controllers, and test equipment daughterboards where the shrouded Tiger Eye housing prevents mis-mating. The 0.100 inch pitch supports signal densities up to 90 lines per connector, and the phosphor bronze contacts handle operating temperatures from -55 °C to +125 °C typical of industrial environments.
How does the TFC-145-02-F-D-A compare to an unshrouded dual-row male header for the same 90-pin layout?
Unlike unshrouded headers, the TFC-145-02-F-D-A includes a plastic shroud that guides the mating female connector onto the 90 pins accurately, reducing field misalignment errors. The shroud also adds mechanical rigidity to the 4.625 inch body and provides partial EMI containment. For field-serviceable racks requiring repeatable 90-pin connections on 0.100 inch pitch, the shrouded variant is the recommended choice.
