Frequently Asked Questions
What is the pin pitch and total contact count of the TFM-137-22-L-D-A-P-TR?
The TFM-137-22-L-D-A-P-TR features a 0.050" (1.27 mm) pitch with 37 positions per row and a dual-row layout, giving 74 total contacts. This high contact density supports complex signal routing in compact embedded systems and industrial PCB designs where space is limited.
How does the Tiger Eye contact design in TFM-137-22-L-D-A-P-TR improve connector reliability?
The Tiger Eye contact geometry uses a bifurcated beam structure that maintains consistent normal force across mating cycles, providing stable contact resistance below 20 mΩ even after repeated insertions. This design is rated for high-reliability applications including defense, aerospace, and industrial systems requiring long service life.
When should engineers select the -TR (tape-and-reel) variant of the TFM-137-22-L-D-A-P-TR for production?
The -TR suffix designates tape-and-reel packaging, which is the correct choice for automated SMT pick-and-place assembly in production volumes exceeding a few hundred units. The 0.050" pitch format is compatible with standard reel feeders, enabling placement rates of hundreds of parts per minute and reducing manual handling errors on high-speed assembly lines.
