Frequently Asked Questions
What contact pitch, density, and current rating does the TFM-109-04-STL-D-LC provide for board interconnects?
The TFM-109-04-STL-D-LC offers 18 pins arranged in 2 rows of 9 at 0.050-inch (1.27 mm) pitch, with each contact rated at 1 A. This dual-row Tiger Eye layout maximizes contact density in a compact footprint for reliable board-to-board connections in aerospace, defense, and industrial high-reliability electronic assemblies.
How does the Tiger Eye contact design improve reliability in vibration and thermal-cycling environments?
The Tiger Eye contact design provides redundant dual-point mating per pin, maintaining a stable 1 A rated connection even under mechanical vibration and thermal cycling from -55°C to +125°C. This redundancy reduces the risk of intermittent contacts, making the TFM-109-04-STL-D-LC suitable for aerospace avionics, military electronics, and ruggedized industrial PCB interconnect systems.
Which high-reliability system designs are best served by the 0.050-inch pitch dual-row TFM-109-04-STL-D-LC?
High-density board-to-board interconnects in test equipment, military avionics, and medical imaging systems benefit from the 0.050-inch pitch dual-row format, which packs 18 pins into a space-efficient footprint at 1 A per circuit. The Tiger Eye contacts and -55°C to +125°C thermal range make it ideal where board compactness and long-service-life reliability are both critical design requirements.
