What are the key features of TSM-125-03-SM-DH-A-K-TR?
- 50-position dual-row surface mount terminal strip on 0.100" (2.54 mm) pitch enabling broad signal and power interconnects on standard PCB grids
- Gold-plated contacts rated at 3A per pin with low contact resistance for reliable signal integrity and power distribution
- RoHS-compliant, rated to 125°C for industrial, telecom, and embedded computing applications requiring high connector reliability
What is TSM-125-03-SM-DH-A-K-TR used for?
The TSM-125-03-SM-DH-A-K-TR is commonly used in backplane systems, PCB-to-PCB signal routing, and high-density wire-to-board connections in industrial automation and embedded computing platforms. The 50-position dual-row configuration consolidates a large number of signal and power lines into a single connector body, reducing PCB real estate and assembly complexity. System designers rely on this terminal strip for data acquisition modules, motor control boards, and test fixtures where repeatable electrical performance is critical.

Frequently Asked Questions
How does TSM-125-03-SM-DH-A-K-TR differ from TSM-125-04-SM-DH-A-K-TR in terms of contact arrangement?
Both parts are 50-position, 0.100" pitch dual-row terminal strips; the suffix digits indicate tape-and-reel packaging variants rather than different pin counts or pitches, so the contact arrangement of 50 positions across 2 rows at 2.54 mm spacing is identical between the two.
What is the per-pin current rating for the TSM-125-03-SM-DH-A-K-TR?
Each gold-plated contact can carry up to 3A continuously, allowing the 50-position connector to handle a mix of signal lines and moderate power rails—such as 3.3 V or 5 V supply rails—without exceeding thermal or resistance specifications.
Which PCB applications benefit most from the 50-position dual-row layout of this terminal strip?
Backplane interconnects, embedded processor daughterboards, and data acquisition front-end cards benefit most, since a single 50-pin dual-row connector at 2.54 mm pitch replaces multiple smaller connectors and simplifies board layout while retaining a standard footprint compatible with common PCB design rules.
Can TSM-125-03-SM-DH-A-K-TR be used in systems exposed to elevated temperatures?
Yes. The connector is rated for continuous operation up to 125°C and meets RoHS environmental standards, making it a dependable choice for industrial control panels, telecom switching line cards, and embedded computing modules operating in thermally demanding environments.
