What are the key features of TSM-123-03-TM-DH-A-K-TR?
- 46 positions in dual-row 2.54 mm pitch SMT format for medium-density board interconnects with large I/O counts
- Gold-plated contacts rated at 3 A per pin enable mixed signal and power distribution across a single connector
- Surface mount tail geometry supports automated pick-and-place reflow assembly for high-volume PCB production
What is TSM-123-03-TM-DH-A-K-TR used for?
TSM-123-03-TM-DH-A-K-TR is used in industrial controllers, embedded computing modules, and data acquisition systems that require a medium-density SMT terminal strip at standard 2.54 mm pitch. Its 46-position dual-row design allows engineers to consolidate many signal and power connections into a single compact SMT body. The connector suits any application where standard through-hole headers are replaced with surface mount alternatives to simplify automated PCB assembly.

Frequently Asked Questions
How many positions and what pitch does TSM-123-03-TM-DH-A-K-TR provide for board interconnects?
TSM-123-03-TM-DH-A-K-TR offers 46 total positions in a dual-row arrangement on a 2.54 mm (0.100 inch) pitch. This standard pitch allows compatibility with a wide range of mating headers and sockets commonly used in industrial, embedded, and data acquisition board designs.
What is the per-contact current rating of TSM-123-03-TM-DH-A-K-TR and how does it affect mixed signal-power routing?
Each gold-plated contact in TSM-123-03-TM-DH-A-K-TR is rated for up to 3 A continuous current, which allows designers to allocate some of the 46 positions for power distribution without requiring a separate power connector. This simplifies board layout and reduces component count in systems with moderate power demands.
Is TSM-123-03-TM-DH-A-K-TR compatible with standard automated SMT reflow assembly?
Yes. TSM-123-03-TM-DH-A-K-TR features a surface mount tail design that is compatible with standard reflow soldering at peak temperatures around 260 °C per J-STD-020. Its form factor supports automated pick-and-place placement, making it straightforward to include in high-volume SMT production without manual insertion steps.
When is TSM-123-03-TM-DH-A-K-TR preferred over a through-hole dual-row header in the same 2.54 mm pitch?
TSM-123-03-TM-DH-A-K-TR is preferred when the design requires fully automated SMT assembly, eliminates wave-soldering or hand-soldering steps, or when mounting a connector on the same side as other SMT components at 2.54 mm pitch. At 46 positions, it matches the I/O count of through-hole equivalents while keeping the board assembly process confined to a single SMT reflow pass.
