What are the key features of TSM-127-01-SM-SH-A?
- 27-position dual-row 2.54 mm (0.100") pitch SMT terminal strip for high-density board connections
- Single-row horizontal mating orientation simplifies connector pairing in low-profile designs
- Surface-mount solder attachment provides robust mechanical retention and eliminates through-hole drilling
- Rated at 1 A per contact with gold-plated contacts for low-contact-resistance signal integrity
What is TSM-127-01-SM-SH-A used for?
TSM-127-01-SM-SH-A is widely used in prototype and production PCBs requiring dense signal routing between boards, such as expansion modules, daughtercards, and test-fixture interfaces. Its surface-mount footprint suits compact consumer electronics and industrial control panels where board real estate is limited. The horizontal single-row mating style also makes it a practical choice for flat-cable termination and sensor-array wiring harnesses.

Frequently Asked Questions
What is the pin pitch and row configuration of the TSM-127-01-SM-SH-A?
The TSM-127-01-SM-SH-A uses a 2.54 mm (0.100 inch) pitch in a 27-position dual-row layout, providing 54 total contact positions in a compact surface-mount footprint suitable for high-density PCB interconnections.
How much current can each contact of the TSM-127-01-SM-SH-A handle in a typical application?
Each contact in the TSM-127-01-SM-SH-A is rated at 1 A continuous current, and with gold-plated terminations the contact resistance stays below 20 mΩ, making it reliable for signal and low-power distribution tasks in embedded systems.
Which PCB assembly processes are compatible with the TSM-127-01-SM-SH-A surface-mount terminal strip?
The TSM-127-01-SM-SH-A is designed for standard SMT reflow soldering processes at peak temperatures up to 260 °C, compatible with lead-free solder paste, and suits pick-and-place automated assembly lines for high-volume production runs.
When should a designer choose TSM-127-01-SM-SH-A over a through-hole connector for the same 27-position requirement?
Choose the TSM-127-01-SM-SH-A when board thickness or component clearance constraints prevent through-hole drilling, when double-sided SMT assembly is used, or when the 2.54 mm pitch density and 1 A per-pin rating meet signal requirements without needing higher-current through-hole pins rated above 3 A.
