What are the key features of TSM-125-03-S-DH-A-K-TR?
- 50-position dual-row design at 0.100" (2.54 mm) pitch delivering high pin-count signal density within a compact SMT footprint for industrial and commercial PCBs
- Surface-mount (SM) termination enabling full compatibility with automated pick-and-place and reflow soldering for high-volume PCB production
- Gold-plated dual-row contacts providing reliable low contact resistance and extended mating cycle durability in demanding interconnect applications
What is TSM-125-03-S-DH-A-K-TR used for?
The TSM-125-03-S-DH-A-K-TR is well-suited for bus interconnect, memory expansion, and daughter card interface applications in embedded computing platforms, industrial controllers, and test-and-measurement equipment requiring 50 positions at 2.54 mm pitch. Its SMT dual-row configuration supports high-volume automated assembly and integrates cleanly with standard 0.100 inch pitch ribbon cable connectors and mating header systems. This terminal strip is also applied in communication equipment chassis and power distribution modules where 50-signal interface density is needed.

Frequently Asked Questions
What is the pin configuration and pitch of the TSM-125-03-S-DH-A-K-TR?
The TSM-125-03-S-DH-A-K-TR has 50 positions arranged in a dual-row layout with a 0.100 inch (2.54 mm) pitch. This standard 2.54 mm pitch ensures interoperability with a wide range of complementary headers, ribbon cable connectors, and prototyping systems used in industrial and commercial PCB designs.
What SMT assembly process is compatible with the TSM-125-03-S-DH-A-K-TR?
The TSM-125-03-S-DH-A-K-TR uses surface-mount termination designed for standard reflow soldering with solder paste stencil application. It is compatible with automated pick-and-place equipment and lead-free reflow profiles up to 260°C, enabling high-throughput production on standard SMT assembly lines without through-hole drilling.
How does the TSM-125-03-S-DH-A-K-TR differ from TSM-125-01-LM-DH-A-K-TR for a high-density PCB layout?
The TSM-125-03-S-DH-A-K-TR and TSM-125-01-LM-DH-A-K-TR both offer 50 positions at 2.54 mm pitch, but differ in end style and lead configuration (03 vs 01 suffix options). The 03-S variant's specific end and lead configuration may offer different PCB standoff heights or lead styles suited to thicker PCBs or specific mounting constraints compared to the 01-LM variant.
For a 50-position bus in an embedded computing design, when is TSM-125-03-S-DH-A-K-TR preferable to a higher-density 1.27 mm pitch connector?
The TSM-125-03-S-DH-A-K-TR at 2.54 mm pitch is preferable when the design needs to interface with standard 0.100 inch ribbon cables or prototyping boards, or when the PCB layout allows the larger footprint. High-density 1.27 mm pitch alternatives reduce PCB area by approximately 50% but require finer soldering tolerances and are less compatible with manual prototyping hardware.
