Frequently Asked Questions
What is the pin pitch and row configuration of the TSM-139-01-L-DV-P-TR?
The TSM-139-01-L-DV-P-TR features a .100" (2.54 mm) pitch dual-row layout with 78 total positions (39 per row), making it suitable for high-density signal routing on standard 0.1-inch grid PCB designs.
What current rating does each pin of the TSM-139-01-L-DV-P-TR support?
Each contact in the TSM-139-01-L-DV-P-TR is rated for up to 2A per pin, with gold-plated contacts ensuring low contact resistance. This supports both signal and moderate power distribution across 78 pins in a compact SMT form factor.
Which assembly process is compatible with the TSM-139-01-L-DV-P-TR surface mount terminal strip?
The TSM-139-01-L-DV-P-TR is designed for surface mount technology (SMT) assembly, supporting automated pick-and-place machines and reflow soldering at standard lead-free reflow temperatures of approximately 260°C peak, enabling high-volume production efficiency.
When would a designer choose TSM-139-01-L-DV-P-TR over a through-hole terminal strip for a backplane application?
A designer would choose the TSM-139-01-L-DV-P-TR when PCB thickness constraints or component density requirements favor SMT over through-hole mounting. The SMT format saves board space, eliminates drilling costs, and allows both sides of the PCB to be utilized, particularly in 78-pin backplane or expansion card designs.
