Frequently Asked Questions
What contact finish does the TSM-125-01-L-DH-A-K-TR use for mating and termination surfaces?
The mating contacts are plated with 10 µin gold over 50 µin nickel for low contact resistance and durability. The termination surface uses matte tin (Sn) with a nickel (Ni) barrier, providing strong solder joint integrity and corrosion protection across industrial temperature ranges.
How many positions does the TSM-125-01-L-DH-A-K-TR provide, and what pitch does it use?
This terminal strip provides 50 positions arranged on a .100" (2.54 mm) pitch in a dual-row surface mount configuration. The 50-pin layout enables dense board connections while maintaining compatibility with standard .100" pitch tooling and mating connectors.
Which PCB assembly methods are compatible with the TSM-125-01-L-DH-A-K-TR, and is tape-and-reel packaging available?
The TSM-125-01-L-DH-A-K-TR is a surface mount component supplied in tape-and-reel (TR) packaging, making it fully compatible with automated pick-and-place assembly lines. The matte tin termination supports standard reflow soldering processes at temperatures up to 260°C per JEDEC MSL guidelines.
