What are the key features of TSM-117-03-LM-DH-A-K-TR?
- 34-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch supporting up to 17 signals per row
- LM (low-profile mated) series contact design minimizing stacked connector height for compact enclosure applications
- Tape and reel packaging compatible with automated pick-and-place assembly for high-volume PCB production
- Dual-row configuration increasing contact density over single-row alternatives in the same PCB footprint length
What is TSM-117-03-LM-DH-A-K-TR used for?
The TSM-117-03-LM-DH-A-K-TR is used in high-density PCB signal interconnect designs where a 34-position dual-row 2.54 mm pitch SMT connector must fit within a compact board layout. It is commonly deployed in embedded processor boards, communication daughter cards, and industrial I/O expansion modules requiring reliable SMT signal routing across 17 parallel paths per row. Its tape-and-reel packaging supports automated assembly lines in consumer electronics, telecommunications, and industrial automation manufacturing.

Frequently Asked Questions
What does the LM suffix indicate in the TSM-117-03-LM-DH-A-K-TR part number?
The LM suffix in the TSM-117-03-LM-DH-A-K-TR denotes the low-profile mated height variant in SAMTEC's TSM series, which reduces the combined stack height of mated connector pairs compared to standard-height contacts. For a 34-position dual-row 2.54 mm pitch SMT connector, the LM variant is chosen when vertical clearance inside an enclosure limits the maximum mated stack height to typically under 8 mm.
How does the 34-position dual-row layout of the TSM-117-03-LM-DH-A-K-TR support high-density signal routing?
With 34 total positions in 2 rows of 17 contacts each at 0.100" (2.54 mm) pitch, the TSM-117-03-LM-DH-A-K-TR routes more signals per unit of PCB edge length than a single-row 34-position connector. This dual-row arrangement is especially useful in embedded computing and FPGA expansion headers where 34 I/O signals must be brought off-board in the shortest possible connector length along a PCB edge.
Is the TSM-117-03-LM-DH-A-K-TR suitable for automated SMT production, and what packaging does it use?
Yes, the TSM-117-03-LM-DH-A-K-TR is supplied in tape and reel (TR) packaging, making it directly compatible with automated pick-and-place equipment used in SMT production lines. The tape-and-reel format ensures consistent connector orientation and protects contacts during high-speed placement, reducing defect rates when assembling 34-position dual-row SMT connectors at 2.54 mm pitch in volume production.
When would a designer choose the TSM-117-03-LM-DH-A-K-TR over a through-hole 34-position dual-row header?
A surface mount TSM-117-03-LM-DH-A-K-TR is preferred over through-hole equivalents when the PCB uses SMT-only assembly processes or when no through-holes are available in the connector zone. The SMT version also eliminates the need to drill 34 dual-row holes (68 total at 2.54 mm pitch), reducing PCB fabrication cost and allowing component placement on both sides of the board beneath the connector footprint.
