Frequently Asked Questions
How many positions and what pitch does the TSM-124-03-SM-DH-A-K-TR provide?
The TSM-124-03-SM-DH-A-K-TR is a 48-position dual-row terminal strip built on a 0.100" (2.54 mm) pitch. This standard pitch accommodates up to 3 A per pin at up to 250 V AC, making it a versatile connector for both signal and moderate-power routing on SMT PCBs.
In which high-density board scenarios does the TSM-124-03-SM-DH-A-K-TR outperform a single-row connector of the same position count?
When 48 signals must connect within a compact board area, the dual-row layout of the TSM-124-03-SM-DH-A-K-TR halves the required connector length compared to a single-row 48-position strip, saving roughly 60 mm of PCB edge space. This is critical in embedded controller stacks and server blade form factors where horizontal real estate is scarce.
What packaging format does TSM-124-03-SM-DH-A-K-TR ship in, and how does the key feature help during assembly?
The connector ships in tape-and-reel (TR) format for automated surface-mount pick-and-place, compatible with standard 8 mm to 16 mm reel widths used in most SMT assembly lines. The key (K) alignment post prevents 180-degree mis-insertion during mating, reducing field failures and rework costs in high-mix production environments.
