Key Features
- Tiger Eye dual-wipe contact system at 0.050" pitch guarantees reliable low-resistance mating across thousands of cycles for mission-critical applications
- 90-position dual-row SMT layout maximizes signal density while minimizing PCB footprint in compact board-to-board interconnect stacks
- Tape-and-reel (TR) packaging supports high-volume automated SMT pick-and-place assembly for efficient production throughput
Applications
The TFM-145-22-H-D-A-P-TR is used in compact board-to-board interconnect applications requiring high pin counts in a minimal 0.050" pitch footprint, such as FPGA expansion cards and embedded compute modules. Its Tiger Eye contact design makes it a reliable choice for defense, aerospace, and industrial boards where connector integrity must be maintained under mechanical vibration and thermal stress. The surface-mount termination and tape-and-reel packaging simplify automated assembly in high-volume PCB production.

Frequently Asked Questions
How many positions does TFM-145-22-H-D-A-P-TR offer, and what pitch is used for board-to-board connections?
The TFM-145-22-H-D-A-P-TR provides 90 contact positions in a dual-row arrangement at 0.050" pitch. This combination delivers a high signal density that is especially useful for FPGA expansion boards and processor modules where routing dozens of differential pairs or single-ended signals across a board-to-board interface requires more than 80 pins in a small area.
For a defense system PCB requiring thousands of mating cycles, why is the Tiger Eye contact preferable over standard beam contacts?
The Tiger Eye contact in the TFM-145-22-H-D-A-P-TR uses a dual-wipe mechanism that maintains low and stable contact resistance over thousands of mating cycles, unlike single-beam contacts that can exhibit increased resistance after repeated use. This durability, combined with the 0.050" pitch and 90-position layout, makes it a trusted choice for defense and aerospace board interconnects subject to frequent maintenance cycles.
Does the tape-and-reel format of TFM-145-22-H-D-A-P-TR affect minimum order quantities for SMT production?
The TR (tape-and-reel) suffix means TFM-145-22-H-D-A-P-TR is packaged for automated SMT assembly, which typically comes in reel quantities of 500 to 1,000 pieces depending on SAMTEC's reel configuration for this 90-position, 0.050" pitch connector. This format is cost-effective for mid-to-high volume production but may require purchasing a full reel minimum, which designers should confirm with their distributor.
