What are the key features of TSM-141-03-STL-DV-P-TR?
- 82-position dual-row .100" (2.54 mm) pitch SMT terminal strip with straight tails for high-density board-to-board interconnect
- Gold-plated contacts rated at 3 A per pin ensuring reliable low-resistance signal and power connections across 82 positions
- Polarization key prevents incorrect mating in stacked card assemblies, reducing field assembly errors in modular embedded systems
What is TSM-141-03-STL-DV-P-TR used for?
The TSM-141-03-STL-DV-P-TR is deployed in modular embedded computing platforms, stackable PCB card assemblies, and industrial I/O expansion systems where a high pin-count 82-position SMT connector with polarization is required. The straight through-hole tails provide mechanical stability during reflow, making it suitable for automated PCB assembly in high-reliability industrial control and test equipment. Its .100" pitch allows integration into existing legacy backplane form factors while supporting modern surface-mount manufacturing processes.

Frequently Asked Questions
How many positions does the TSM-141-03-STL-DV-P-TR provide and how are they physically arranged on the PCB?
The TSM-141-03-STL-DV-P-TR offers 82 positions arranged in a dual-row format on a .100" (2.54 mm) pitch, giving 41 pins per row. This configuration is standard for legacy backplane and stacking card form factors, allowing direct mating with complementary TSW or similar .100" dual-row receptacles in embedded computing and industrial I/O chassis designs.
What current rating do the contacts of the TSM-141-03-STL-DV-P-TR support and how does this affect mixed signal-power pin usage?
Each contact on the TSM-141-03-STL-DV-P-TR is rated at 3 A continuous current with gold plating for low contact resistance. In mixed-use designs where some of the 82 pins carry power rails and others carry logic signals, the 3 A per-pin rating provides ample headroom for 3.3 V or 5 V power distribution without requiring dedicated power connectors alongside the signal connector.
Over what temperature range does the TSM-141-03-STL-DV-P-TR maintain reliable electrical contact?
The TSM-141-03-STL-DV-P-TR operates reliably from -55°C to +125°C, a 180°C span that covers industrial, military, and transportation system requirements. This wide thermal tolerance ensures the dual-row SMT connector maintains consistent contact force and low resistance across environments ranging from cold-start outdoor enclosures to elevated-temperature electronics bays in industrial machinery.
How does the TSM-141-03-STL-DV-P-TR compare to the TSM-141-02-TL-DV-P-TR for a stacking card application requiring polarization?
The TSM-141-03-STL-DV-P-TR (STL suffix) includes straight through-hole tails and a polarization feature, while the TSM-141-02-TL-DV-P-TR (TL suffix) uses a different tail style without the same orientation key. For stacking card applications where incorrect connector orientation would short power rails across 82 pins at 3 A each, the STL variant's polarization feature provides an additional safeguard not present on the TL variant.
