Frequently Asked Questions
What is the position count and pitch of the TFC-145-02-LM-D-A-K and what bus widths does it support?
The TFC-145-02-LM-D-A-K provides 90 positions in a dual-row layout at 0.050" (1.27 mm) pitch, supporting 45 differential pairs or up to 90 single-ended signals in a single connector footprint. This capacity suits wide FPGA parallel buses, DDR memory interfaces, and multi-channel ADC data paths on high-performance embedded computing and signal processing boards.
How does the TFC-145-02-LM-D-A-K balance cost and reliability for high-volume FPGA board production?
The TFC-145-02-LM-D-A-K uses SAMTEC's cost-effective Tiger Eye contact design, which provides bifurcated high-normal-force contacts at 0.050" pitch without the premium pricing of high-speed or shielded alternatives. For 90-position interfaces on FPGA evaluation kits, embedded computing modules, and industrial control backplanes produced in volume, this connector reduces BOM cost while maintaining reliable contact resistance and mechanical durability over multiple mating cycles.
Which SAMTEC mating headers are compatible with TFC-145-02-LM-D-A-K for configurable board-to-board stack heights?
The TFC-145-02-LM-D-A-K mates with SAMTEC TFC and TSM series mating headers at 0.050" (1.27 mm) pitch in 90-position dual-row configurations. Compatible headers are offered in multiple stack heights from approximately 0.1" to 0.5" or more, allowing engineers to choose the mechanical clearance needed for specific backplane, daughtercard, or FPGA mezzanine designs without changing the PCB footprint.
