Frequently Asked Questions
What is the pitch and row configuration of the TSM-128-04-H-DH-A-K-TR connector?
The TSM-128-04-H-DH-A-K-TR uses a 2.54 mm (0.100") pitch dual-row layout providing 56 total positions, making it compatible with standard 0.100" grid PCB footprints used across a wide range of embedded and industrial designs.
How much current can each pin of the TSM-128-04-H-DH-A-K-TR carry safely?
Each pin of the TSM-128-04-H-DH-A-K-TR is rated at approximately 1.0 A continuous current for signal use. The gold-plated contacts maintain low contact resistance over thousands of mating cycles, ensuring stable performance in 3.3 V and 5 V digital signal applications.
Which assembly processes are supported by the tape-and-reel packaging of TSM-128-04-H-DH-A-K-TR?
The -TR suffix indicates tape-and-reel packaging, which supports automated SMT pick-and-place assembly lines. This reduces manual handling errors and speeds production throughput for high-volume PCB assembly running at typical line speeds of 5,000 to 10,000 components per hour.
Is TSM-128-04-H-DH-A-K-TR suitable for backplane interconnect designs requiring more than 50 signal pins?
Yes. With 56 positions arranged in a dual-row, 2.54 mm pitch surface mount footprint, TSM-128-04-H-DH-A-K-TR is well suited for backplane and daughter-card interconnects needing 56 signal or power lines in a compact SMT package, saving board space compared to through-hole alternatives.
