Frequently Asked Questions
How many positions does the TSM-125-04-LM-DH-A-K-TR offer and what is its contact pitch?
The TSM-125-04-LM-DH-A-K-TR provides 50 positions arranged in a dual-row configuration with a 0.100 inch (2.54 mm) pitch. This standard pitch spacing is compatible with a wide range of mating connectors and supports reliable high-density interconnects in surface mount PCB designs.
Which PCB assembly processes are compatible with this SAMTEC terminal strip?
This connector uses a surface mount technology (SMT) footprint and is supplied in tape-and-reel (TR) packaging, making it fully compatible with automated pick-and-place assembly and reflow soldering processes. The SMT design supports placement on standard 1.6 mm PCBs and works within typical reflow profiles up to 260°C peak temperature.
When should a designer choose the TSM-125-04-LM-DH-A-K-TR over a through-hole terminal strip?
Designers should select this SMT terminal strip when board space is limited and a low-profile connector is required, since the surface mount design eliminates the need for drilled through-holes and reduces PCB layer stackup complexity. The 50-position dual-row format delivers high contact density in a compact SMT footprint, making it preferable for high-volume automated production versus manual through-hole insertion, especially in designs targeting boards with 2 mm or less available height clearance.
