Frequently Asked Questions
What is the position count and pitch of the TSM-120-03-T-DH-P-TR, and how does the dual-row layout benefit PCB density?
The TSM-120-03-T-DH-P-TR provides 40 positions in a dual-row arrangement at .100" (2.54 mm) pitch, with 20 positions per row. This dual-row layout allows engineers to route twice the signals in the same board length compared to a single-row connector, improving density for backplane and embedded module designs.
Does the TSM-120-03-T-DH-P-TR support automated SMT assembly, and what packaging format is available?
Yes, the TSM-120-03-T-DH-P-TR is supplied in tape-and-reel (-TR) format compatible with automated pick-and-place equipment for SMT reflow assembly. The press-fit tail contacts provide reliable solder joint attachment across standard reflow temperature profiles, suitable for production volumes requiring consistent quality.
How does the TSM-120-03-T-DH-P-TR compare to the TSM-125-01-TL-DH-P-TR in terms of position count and design choice?
The TSM-120-03-T-DH-P-TR offers 40 positions while the TSM-125-01-TL-DH-P-TR provides 50 positions, both at .100" (2.54 mm) pitch in a dual-row SMT terminal strip. Designers choose the 40-position variant when fewer signal connections are needed, reducing board footprint and connector cost without sacrificing the dual-row density advantage.
