What are the key features of TSM-141-03-LM-DV-P-TR?
- 82-position dual-row 2.54 mm pitch SMT terminal strip delivering 41 contacts per row for high-density board connectivity
- Low-mating-force (LM) pin profile engineered for repeated insertion cycles in test fixture and programming socket applications
- Tape-and-reel (TR) packaging enabling high-speed automated pick-and-place SMT assembly for volume production
What is TSM-141-03-LM-DV-P-TR used for?
The TSM-141-03-LM-DV-P-TR is used in in-circuit test (ICT) fixtures, boundary-scan adapters, and programming board interfaces where the 82-position low-mating-force dual-row strip must withstand thousands of repeated connect and disconnect cycles. Its 2.54 mm SMT footprint also serves backplane interconnects and industrial controller boards requiring reliable, high-density surface mount terminal arrays in volume automated production environments.

Frequently Asked Questions
What makes the LM (low-mating-force) pin profile of the TSM-141-03-LM-DV-P-TR advantageous in test fixtures?
The low-mating-force (LM) pin profile reduces the insertion force required to mate the 82-position connector, preventing damage to fine-pitch receptacles and extending the lifespan of test fixture sockets subjected to thousands of repeated mate/unmate cycles. This is especially valuable in ICT and programming fixtures where the connector may be engaged hundreds of times per day over months of production testing.
How does the 2.54 mm pitch of the TSM-141-03-LM-DV-P-TR compare to finer-pitch alternatives for dense PCB designs?
The 2.54 mm (0.100 inch) pitch of the TSM-141-03-LM-DV-P-TR is a legacy standard pitch that offers easier manual soldering, broader tooling availability, and mechanical robustness compared to finer-pitch 1.27 mm or 2.00 mm alternatives. For 82-position dual-row layouts requiring high contact reliability without the yield sensitivity of fine-pitch SMT soldering, the 2.54 mm standard remains a practical choice in industrial and instrumentation applications.
What reel quantity and SMT assembly process considerations apply when ordering the TSM-141-03-LM-DV-P-TR in volume?
The TSM-141-03-LM-DV-P-TR is packaged on tape and reel (TR suffix), typically available in reel quantities of 500 or 1000 pieces, suitable for continuous pick-and-place operation on SMT lines. The 82-position format requires accurate paste deposition across 82 pads in a dual-row pattern at 2.54 mm pitch, and the reel packaging ensures consistent part orientation for nozzle pickup without manual loading interruptions during volume production runs.
