Frequently Asked Questions
What pitch and position count does the TSM-127-04-H-DH-A-K-TR provide for board interconnect designs?
The TSM-127-04-H-DH-A-K-TR offers 54 positions arranged in a dual-row layout at a standard 0.100-inch (2.54mm) pitch. This combination gives designers 54 signal or power contacts on a single surface mount terminal strip, making it well suited for dense multi-signal board interconnect applications.
How does tape-and-reel packaging affect production planning for the TSM-127-04-H-DH-A-K-TR?
The TR (tape-and-reel) suffix indicates the TSM-127-04-H-DH-A-K-TR ships in reel format compatible with standard pick-and-place machines. This allows automated placement at throughput rates typical for SMT lines, reducing per-unit placement time compared to tray-packaged alternatives for high-volume runs of 1,000 units or more.
Which PCB assembly processes are supported by the surface mount termination style of this connector?
The surface mount termination on the TSM-127-04-H-DH-A-K-TR supports standard reflow soldering at typical lead-free peak temperatures of 260°C. No through-hole drilling is required, which simplifies board fabrication and reduces layer stack-up costs compared to through-hole terminal strip alternatives of similar position count.
When should a designer choose the TSM-127 series over a through-hole terminal strip with the same 0.100-inch pitch?
The TSM-127 series surface mount format is preferred when PCB layer count must be minimised, or when component placement is single-sided to reduce assembly steps. A 54-position SMT strip like the TSM-127-04-H-DH-A-K-TR eliminates drilled via barrels, saving roughly 54 plated-through holes and the associated board fabrication cost on designs where Z-axis clearance below the board is constrained.
