Frequently Asked Questions
How many positions and what pitch does the TSM-121-04-TL-DH-A-K-TR provide?
The TSM-121-04-TL-DH-A-K-TR provides 42 total positions arranged in a dual-row layout with 2.54 mm (0.100") pitch, giving 21 positions per row for organized, high-density surface mount signal routing on PCBs.
For which embedded computing or industrial applications is the TSM-121-04-TL-DH-A-K-TR best suited?
This 42-position 2.54 mm pitch dual-row surface mount terminal strip is well suited for embedded computing modules, industrial backplane interconnects, data acquisition systems, and telecommunications line cards requiring dense, reliable signal connections at standard 0.100" pitch spacing.
When would a designer choose TSM-121-04-TL-DH-A-K-TR over a through-hole terminal strip of similar pin count?
Choosing the TSM-121-04-TL-DH-A-K-TR surface mount version over a through-hole alternative eliminates the need for drilling 42 holes in the PCB, reduces board thickness constraints, and enables full reflow soldering assembly, saving manufacturing time and cost especially in high-volume or space-constrained designs.
