Frequently Asked Questions
How many signal connections does the TSM-128-03-TL-DH-A-P-TR support in a dual-row configuration?
The TSM-128-03-TL-DH-A-P-TR provides 56 total positions arranged in 2 rows of 28 pins each on a .100" (2.54 mm) pitch. This high-density layout supports 56 simultaneous signal or power connections, making it ideal for parallel bus interfaces, sensor arrays, and multi-channel power distribution in embedded system designs.
Which assembly processes are supported by TSM-128-03-TL-DH-A-P-TR, and how does its packaging help production efficiency?
This connector comes in tape-and-reel (TR) packaging, enabling automated pick-and-place SMT assembly with reflow soldering. The surface-mount termination eliminates through-hole drilling for all 56 positions, significantly reducing PCB fabrication cost and assembly cycle time in high-volume production environments handling thousands of boards per day.
How does the TSM-128-03-TL-DH-A-P-TR compare to a 56-position through-hole connector for backplane applications?
Compared to a through-hole alternative, the TSM-128-03-TL-DH-A-P-TR offers a lower PCB profile and avoids drilling 56 holes per connector, reducing board cost. Its SMT footprint also enables double-sided component placement. However, for applications requiring higher mechanical pull-out strength beyond 2 N per pin, a through-hole variant may be specified instead.
