Key Features
- 90-position dual-row Tiger Eye terminal strip at 0.050" (1.27 mm) pitch providing the highest pin count in the TFC series for wide-bus, high-density SMT interconnect applications
- Tiger Eye bifurcated contact design delivers robust normal force and consistent low-resistance mating over repeated insertion cycles, ensuring signal integrity in vibration-prone environments
- Cost-effective alternative to premium fine-pitch connectors for 90-signal parallel interfaces on FPGA boards, backplanes, and industrial computing modules without sacrificing SAMTEC reliability
Applications
The TFC-145-02-LM-D-A-K targets wide-bus FPGA interface boards, DSP processing modules, and high-density backplane interconnects that require 90 signals at 0.050" pitch in a compact SMT footprint. Its Tiger Eye contact design supports repeated mating cycles needed in field-replaceable computing modules, making it suitable for industrial automation controllers and defense electronics. Signal acquisition systems and radar data processing boards also use this terminal strip for its high position count and cost-effective Tiger Eye contact reliability.

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.
