Frequently Asked Questions
What is the pitch and position count of the TSM-125-04-S-DH-A-K-TR, and how do these specs affect PCB layout?
The TSM-125-04-S-DH-A-K-TR has a 0.100 inch (2.54 mm) pitch with 50 total positions arranged in a dual-row configuration of 25 positions per row. The 2.54 mm pitch aligns with standard PCB grid layouts, simplifying routing, and the 50-position count allows connection of up to 50 signal or power lines in a relatively compact surface mount footprint.
Is the TSM-125-04-S-DH-A-K-TR compatible with automated SMT assembly lines?
Yes, the TSM-125-04-S-DH-A-K-TR is a surface mount component packaged in tape and reel format (TR suffix), making it fully compatible with automated pick-and-place equipment and reflow soldering processes. The 0.100 inch pitch pads are standard, allowing standard SMT stencil design with typical solder paste volumes for 2.54 mm pitch components.
In which industrial or telecom designs is the TSM-125-04-S-DH-A-K-TR typically deployed?
This 50-position SAMTEC terminal strip is commonly used in industrial automation controllers, PLC I/O modules, telecom backplane interconnects, and embedded computing expansion boards. The dual-row SMT design supports 50-line signal interfaces in compact 0.100 inch pitch layouts, making it suitable for data acquisition systems that need a dense connector with reflow-compatible termination.
How does the TSM-125-04-S-DH-A-K-TR compare to through-hole alternatives of similar pitch and position count?
Compared to through-hole versions at 0.100 inch pitch, the TSM-125-04-S-DH-A-K-TR surface mount design reduces PCB drilling requirements and enables placement on single-sided boards, saving approximately 1–2 mm in board thickness. SMT mounting also allows shorter signal paths, which can improve signal integrity at frequencies above 100 MHz in high-speed digital designs.
