Frequently Asked Questions
What pitch and how many positions does the TSM-125-03-H-DH-A-K-TR terminal strip provide?
The TSM-125-03-H-DH-A-K-TR is a 50-position dual-row terminal strip on 0.100-inch (2.54mm) pitch, compatible with standard 2.54mm grid PCB layouts for board-to-board signal interconnects in industrial and communications equipment.
What does the tape-and-reel (TR) suffix on TSM-125-03-H-DH-A-K-TR mean for production assembly?
The TR suffix indicates tape-and-reel packaging, allowing the 50-position SMT connector to be fed through automated pick-and-place machines for high-volume PCB assembly lines, reducing handling time and improving placement accuracy compared to tray-packaged parts.
Which mating connector from SAMTEC is compatible with the TSM-125-03-H-DH-A-K-TR in a board stacking application?
The TSM-125-03-H-DH-A-K-TR mates with SAMTEC SFM-series socket strips on 0.100-inch (2.54mm) pitch, providing a 50-pin dual-row board-to-board interconnect solution with gold-plated contacts rated for multiple mating cycles in stacked PCB assemblies.
