What are the key features of TSM-120-03-F-DH-A-K-TR?
- 40-position dual-row flat (F) SMT terminal strip with 2.54 mm pitch enabling dense board-to-board signal routing
- Gold-plated (A) contacts delivering contact resistance under 20 milliohms and superior corrosion resistance for reliable long-term performance
- Tape-and-reel (TR) packaging supporting automated pick-and-place assembly in high-volume SMT production environments
What is TSM-120-03-F-DH-A-K-TR used for?
The TSM-120-03-F-DH-A-K-TR is suited for board-to-board and wire-to-board connections in embedded systems, industrial controllers, and communications equipment requiring a flat-profile 40-position 2.54 mm pitch surface mount connector. Its dual-row layout efficiently routes 40 signal or power channels in a minimal PCB footprint, making it a strong choice for backplane interfaces, sensor interface boards, and data acquisition hardware.

Frequently Asked Questions
What does the 'F' designator mean in the TSM-120-03-F-DH-A-K-TR part number?
The 'F' in the SAMTEC TSM series part number designates a flat (standard) body height, as opposed to longer standoff variants. This flat profile keeps the connector within approximately 3.6 mm above the PCB surface, which is important for low-profile or space-constrained enclosures using 40-position dual-row SMT connectors.
How many signal channels can the TSM-120-03-F-DH-A-K-TR accommodate, and what is its contact pitch?
This connector provides 40 positions arranged in 2 rows of 20, with a 2.54 mm (0.100 inch) pitch between contacts. Each contact is rated for up to 3 A and 250 V AC/DC, accommodating 40 independent signal or power channels in a dual-row surface mount footprint.
When would the TSM-120-03-F-DH-A-K-TR be preferred over a through-hole equivalent for PCB assembly?
The SMT version is preferred when using fully automated reflow soldering lines at up to 260°C peak, since it eliminates the need for manual through-hole insertion, reduces board drilling costs, and allows component placement on both sides of the PCB, streamlining assembly of 40-position dual-row connector footprints.
