What are the key features of TSM-128-05-H-SH-A?
- 28 positions in dual-row, 2.54mm (0.100") pitch SMD layout enabling high pin-count board-to-board signal routing in minimal PCB area
- Horizontal (H) orientation with solder-hold-down (SH) tabs provides strong mechanical retention and prevents connector rotation during reflow soldering
- Gold-plated contacts rated at 2A per pin deliver reliable low-resistance interconnects for signal and light power distribution
- Surface-mount construction compatible with standard reflow soldering processes, eliminating through-hole drilling and reducing assembly cost
What is TSM-128-05-H-SH-A used for?
The TSM-128-05-H-SH-A is used in embedded system PCBs, development boards, and industrial control modules where a high-density 28-pin SMD edge connector must mate with 0.100" pitch headers or breakout boards. Its horizontal orientation and solder-hold-down tabs make it a reliable choice for test jigs, data-acquisition daughter cards, and FPGA evaluation platforms where mechanical robustness and 2A-per-pin current capacity are required. The surface-mount form factor enables automated assembly with standard pick-and-place equipment.

Frequently Asked Questions
What pin count, pitch, and current rating define the TSM-128-05-H-SH-A connector?
The TSM-128-05-H-SH-A has 28 positions arranged in a dual-row configuration on a 2.54mm (0.100") pitch. Each pin is rated at 2A, with gold-plated contacts that ensure low contact resistance and reliable signal integrity in SMD horizontal-mount terminal strip applications.
How do the SH (solder-hold-down) tabs on TSM-128-05-H-SH-A improve PCB assembly reliability?
The SH solder-hold-down tabs anchor the TSM-128-05-H-SH-A mechanically to the PCB through 2 additional solder points, preventing rotation or lift-off during reflow at temperatures up to 260°C. This significantly improves co-planarity and mating force resistance in assembled boards, especially for 28-position connectors subject to repeated plug-in cycles of up to 30 mates.
In which system-level designs is TSM-128-05-H-SH-A typically used as an edge or expansion connector?
TSM-128-05-H-SH-A is commonly used in FPGA development boards, microcontroller expansion headers, and industrial I/O daughter-card interfaces where 28 pins at 0.100" pitch meet board-to-board signal routing requirements. Its 2A-per-pin current rating supports mixed signal-and-power buses, such as GPIO banks plus 3.3V or 5V supply rails on test-jig and data-acquisition PCBs.
When does TSM-128-05-H-SH-A offer an advantage over through-hole equivalents for production assemblies?
The surface-mount construction of TSM-128-05-H-SH-A allows it to be placed by automated pick-and-place equipment and reflowed alongside other SMD components, eliminating the separate wave-soldering or hand-soldering step required for through-hole 28-pin strips. This reduces assembly cycle time by approximately one process step per board and removes the need for 28 drilled holes, saving roughly 0.5 mm² of board space per pin.
