What are the key features of TFM-145-22-FM-D-A-P-TR?
- Tiger Eye contact system provides reliable 0.050" pitch signal interconnect with gold plating for gas-tight, low-resistance connections in demanding environments
- Dual-row 90-position (45 per row) layout maximizes signal channel density per unit PCB area for high-count FPGA, DSP, and backplane interfaces
- Flush-mount (FM) profile minimizes protruding height above PCB surface, enabling extremely low-clearance stacked board configurations and slim enclosure designs
What is TFM-145-22-FM-D-A-P-TR used for?
The TFM-145-22-FM-D-A-P-TR is designed for high-density board-to-board signal routing in compact computing modules, military electronics, and advanced telecommunications equipment where flush-mount connectivity at 0.050-inch pitch is critical. Its 90-position dual-row layout supports FPGA daughter card interfaces, multi-channel data acquisition systems, and rugged embedded controllers operating across wide temperature ranges. Tape-and-reel packaging ensures seamless, high-throughput automated SMT assembly for production-scale deployments.

Frequently Asked Questions
What distinguishes the FM (flush-mount) profile of TFM-145-22-FM-D-A-P-TR from standard-height TFM variants?
The FM flush-mount profile reduces the connector body height to near-zero above the PCB surface compared to standard-height TFM variants, allowing stacked PCB assemblies with inter-board gaps smaller than 2 mm. This is critical in ruggedized or slim-form-factor enclosures where standard 0.050-inch pitch connectors with taller bodies cannot meet clearance requirements across 90 dual-row positions.
Which signal-intensive designs benefit from the 90-position dual-row layout of TFM-145-22-FM-D-A-P-TR?
Designs requiring more than 80 simultaneous signal channels benefit most, including FPGA I/O expansion boards routing 90 digital or analog signals, multi-channel oscilloscope front-end modules, military radar signal processors, and communications backplanes needing 45 pins per row at 0.050-inch pitch without increasing the connector's overall PCB footprint width.
When is TFM-145-22-FM-D-A-P-TR a preferred alternative to a standard-pitch 0.100-inch connector for board-to-board links?
TFM-145-22-FM-D-A-P-TR is preferred over 0.100-inch pitch connectors when board space is constrained, since its 0.050-inch pitch achieves the same 90-pin count in roughly half the linear board length. For example, 90 pins at 2.54 mm pitch would span 114 mm per row, while the 0.050-inch pitch spans only 57 mm per row, directly reducing PCB size and signal trace routing complexity.
