Frequently Asked Questions
How many positions does the TSM-127-04-F-DH-A-K-TR provide, and what is its row arrangement?
The TSM-127-04-F-DH-A-K-TR provides 54 positions arranged in a dual-row configuration with 2.54 mm (0.100 inch) pitch. This layout gives designers 27 contacts per row, enabling high-density signal routing in compact PCB-to-PCB interconnect designs for test equipment and embedded computing modules.
What current rating applies to each pin of the SAMTEC TSM-127-04-F-DH-A-K-TR terminal strip?
Each pin of the TSM-127-04-F-DH-A-K-TR is rated at 1A, making the connector suitable for mixed signal and low-power digital bus connections. With 54 positions, the total aggregate current capacity supports multi-rail power distribution alongside high-speed digital signals on backplane and mezzanine card designs.
Why choose tape-and-reel packaging for the TSM-127-04-F-DH-A-K-TR in volume production?
The -TR (tape-and-reel) suffix designates packaging compatible with standard SMT pick-and-place equipment, allowing automated placement at rates exceeding 1000 components per hour on modern assembly lines. This reduces hand-placement errors for the 54-pin dual-row SMT footprint and lowers assembly cost per unit in high-volume production runs.
