What are the key features of TSM-140-03-S-DV-P-TR?
- 80-position dual-row 0.100 inch pitch terminal strip delivers maximum signal density in a compact SMT footprint
- Single-shroud (S) variant provides polarized mating guidance to prevent misalignment during cable or board-to-board connection
- Tape-and-reel (TR) packaging enables high-speed automated placement for mass-production PCB assembly lines
What is TSM-140-03-S-DV-P-TR used for?
TSM-140-03-S-DV-P-TR is suited for high-density board-to-board and cable-to-board interconnects in industrial computers, FPGA carrier boards, and modular test systems requiring a large number of signal lines in a polarized surface-mount connector. The shrouded 80-pin configuration reduces mating errors during field installation, and the tape-and-reel packaging supports automated manufacturing of high-volume electronic assemblies.

Frequently Asked Questions
How does the shrouded (S) variant TSM-140-03-S-DV-P-TR differ from the TSM-140-03-T-DV-P-TR in mating reliability?
The shrouded (S) configuration adds a plastic housing wall around the 80 contacts, guiding the mating connector into the correct position and preventing the 2.54 mm pitch pins from bending during repeated plug/unplug cycles. The unshrouded (T) variant lacks this guide, making the shrouded version preferable in field-serviceable enclosures with frequent cable swaps.
What current rating should designers assume for each pin of the TSM-140-03-S-DV-P-TR when routing power lines?
SAMTEC TSM series surface-mount terminal strips on 0.100 inch pitch are rated for approximately 3 A per contact under free-air conditions. For an 80-position connector where multiple pins are used for power distribution, designers should verify PCB trace width and connector derating curves at the operating temperature, typically -55°C to +125°C.
In which board-level applications does an 80-pin dual-row 0.100 inch SMT strip outperform a pair of 40-pin connectors?
A single 80-pin TSM-140-03-S-DV-P-TR occupies less PCB real estate and requires only one reflow operation compared to two separate 40-pin connectors, reducing pick-and-place cycle time by 50% per board. Applications such as FPGA mezzanine cards, memory expansion boards, and backplane signal distribution benefit from the single-connector approach, as it also simplifies harness assembly.
