Frequently Asked Questions
What is the pitch and row configuration of the TSM-125-03-STL-DH-A-K-TR?
The TSM-125-03-STL-DH-A-K-TR uses a 0.100" (2.54 mm) pitch dual-row arrangement, providing 50 total positions across 2 rows of 25 contacts each, making it suitable for high-density signal routing on standard PCB layouts.
Which PCB assembly processes are compatible with the TSM-125-03-STL-DH-A-K-TR surface mount tails?
This connector supports standard SMT reflow soldering processes; its through-hole tails additionally allow wave solder or selective solder attachment, giving assembly engineers flexibility to achieve reliable solder joints across 50 positions without manual rework.
When would TSM-125-03-STL-DH-A-K-TR be preferred over a conventional through-hole terminal strip in a backplane design?
In space-constrained backplane designs requiring automated SMT assembly, the TSM-125-03-STL-DH-A-K-TR's surface-mount footprint with stabilizing tails reduces board real estate while maintaining mechanical strength across all 50 contact positions, cutting assembly cycle time compared to manual through-hole insertion.
