Key Features
- 90-position dual-row layout at 0.050 inch pitch providing extremely high signal density for backplane and cable harness interconnects
- Tiger Eye contact geometry delivering reliable wipe-action mating and stable low contact resistance across repeated insertion cycles
- Female contact orientation in FM format enabling secure mating with standard 0.050 inch pitch male headers on mating boards
- Tape-and-reel packaging supporting high-volume automated pick-and-place assembly for cost-effective production of embedded system boards
Applications
The TFC-145-02-FM-D-A-K-TR is designed for high-density backplane interconnects, FPGA daughtercard interfaces, and network switch line cards where 90 signals must pass through a compact 0.050 inch pitch dual-row connector footprint. Its tape-and-reel format enables automated SMD assembly in volume production of server expansion cards, industrial I/O modules, and communication boards requiring dense dual-row cable termination. The Tiger Eye contact design maintains reliable connectivity across vibration and thermal cycling environments common in rack-mount and embedded computing applications.

Frequently Asked Questions
How many positions and rows does TFC-145-02-FM-D-A-K-TR have, and what is its pitch?
The TFC-145-02-FM-D-A-K-TR has 90 positions arranged in 2 rows at 0.050 inch (1.27 mm) pitch. With 45 contacts per row, this connector accommodates 90 discrete signals in a footprint roughly equivalent to a 45-position 0.100 inch connector, enabling significant board space savings in high-density embedded and networking designs.
What packaging format does TFC-145-02-FM-D-A-K-TR use and how does it affect assembly efficiency?
The TFC-145-02-FM-D-A-K-TR is supplied in tape-and-reel format, enabling automated pick-and-place placement on SMD production lines at high throughput. This eliminates manual connector insertion for 90-position parts, reducing assembly cycle time and placement errors in volume production of server boards, communication equipment, and industrial I/O expansion modules.
How does the Tiger Eye contact in TFC-145-02-FM-D-A-K-TR improve interconnect reliability at 0.050 inch pitch?
Tiger Eye contacts in the TFC-145-02-FM-D-A-K-TR feature a precision-formed socket geometry that creates a wiping action as the mating male pin is inserted. This wipe clears surface oxides from the contact interface, producing stable contact resistance below a few milliohms across all 90 positions even after repeated mating cycles or exposure to mild corrosive environments in industrial settings.
When is TFC-145-02-FM-D-A-K-TR a better choice than a 0.100 inch pitch connector for the same application?
Designers should choose the TFC-145-02-FM-D-A-K-TR over a 0.100 inch pitch connector when PCB real estate is constrained and 90 or more signals must be routed through a single connector. The 0.050 inch pitch dual-row layout uses approximately 25% of the board area required by a 90-position 0.100 inch pitch single-row connector, which is critical in compact FPGA boards, SoC expansion headers, and rack-mount blade designs where connector footprint directly limits routing channel density.
