Applications
TSM-115-03-SM-DH-A-K-TR is widely used in industrial control boards and communication equipment where reliable board-to-board or wire-to-board connections are required. Its dual-row 30-position layout makes it ideal for data acquisition systems, backplane interconnects, and test and measurement interfaces. The surface mount with through-hole tail design provides extra mechanical stability in high-vibration environments such as automotive electronics and ruggedized industrial panels.

Frequently Asked Questions
What is the pitch and total number of positions on the TSM-115-03-SM-DH-A-K-TR connector?
The TSM-115-03-SM-DH-A-K-TR features a 0.100" (2.54 mm) pitch with 30 total positions arranged in a dual-row configuration, providing high-density interconnection capability in a compact surface mount form factor.
What voltage and current ratings does the TSM-115-03-SM-DH-A-K-TR support?
The connector supports a working voltage of 350V AC and a current rating of 3A per contact. Gold-plated contacts with 30 µin plating thickness ensure low contact resistance and reliable signal integrity over thousands of mating cycles.
Which PCB assembly processes are compatible with the TSM-115-03-SM-DH-A-K-TR tape-and-reel packaging?
The TR (tape-and-reel) suffix indicates this connector is packaged for automated surface mount assembly lines supporting pick-and-place equipment. The SM-DH mounting style combines surface mount pads with through-hole tails, allowing simultaneous reflow soldering with mechanical anchoring for high-vibration environments rated up to 85°C operating temperature.
How does the dual-row SM-DH design of the TSM-115-03-SM-DH-A-K-TR improve board retention compared to single-row options?
The SM-DH (surface mount with dual through-hole tails) design anchors the 30-position, 0.100" pitch connector at 4 mechanical points, providing significantly greater pull strength exceeding 10 lb compared to surface-only mounting. This is critical in connectors experiencing repeated mating cycles or mechanical stress in industrial and automotive applications.
When would a designer choose TSM-115-03-SM-DH-A-K-TR over a standard through-hole terminal strip?
Designers select the TSM-115-03-SM-DH-A-K-TR when boards require reflow-compatible assembly with 30 positions at 2.54 mm pitch while maintaining mechanical robustness. Compared to pure through-hole strips, the SM-DH construction reduces PCB drilling requirements and supports higher-density layouts, making it suitable for compact industrial I/O boards and data acquisition modules where board space is limited.
