What are the key features of TSM-121-01-F-DH-A-K-TR?
- 42-position dual-row layout on industry-standard 0.100" (2.54 mm) pitch supports dense signal routing in surface mount board-to-board applications
- Gold (Au) contact finish (F suffix) provides low-contact resistance and superior corrosion resistance for high-reliability signal connections
- Tape-and-reel (TR) packaging enables high-throughput automated SMT pick-and-place assembly, reducing production cycle time for volume builds
What is TSM-121-01-F-DH-A-K-TR used for?
The TSM-121-01-F-DH-A-K-TR is deployed in backplane interconnects, industrial I/O modules, and embedded computing boards requiring 42 signal positions at 0.100" pitch SMT connectivity. Its gold-plated contacts maintain reliable signal integrity across thousands of mating cycles in test and measurement equipment and data acquisition systems. The tape-and-reel format supports automated high-volume PCB assembly in telecommunications and industrial control products.

Frequently Asked Questions
What contact finish does TSM-121-01-F-DH-A-K-TR use, and why does it matter for signal integrity?
The TSM-121-01-F-DH-A-K-TR uses gold (Au) plating on its contacts, indicated by the F suffix in the part number. Gold provides a contact resistance below 20 milliohms and resists oxidation over thousands of mating cycles, ensuring stable signal integrity in 42-position connectors used in test equipment and embedded computing applications where signal loss must be minimized.
How many positions does TSM-121-01-F-DH-A-K-TR provide, and how are they arranged?
The TSM-121-01-F-DH-A-K-TR provides 42 total positions arranged in a dual-row configuration at 0.100" (2.54 mm) pitch, with 21 positions per row. This high pin-count arrangement supports dense signal routing for multi-channel data buses, parallel interfaces, or mixed signal-and-power interconnects in industrial and computing PCB assemblies.
For a high-volume SMT production line, what packaging advantage does TSM-121-01-F-DH-A-K-TR offer?
The TR (tape-and-reel) packaging of TSM-121-01-F-DH-A-K-TR is directly compatible with automated pick-and-place machines, eliminating hand-loading of the 42-position connector during SMT assembly. Reel quantities typically contain several hundred parts, enabling continuous placement runs that reduce assembly time per board by approximately 10 to 30 seconds versus manual insertion of comparable through-hole headers.
