Frequently Asked Questions
How many positions and what pitch does the TSM-125-04-SM-DH-A-K-TR offer?
The TSM-125-04-SM-DH-A-K-TR provides 50 positions arranged in a dual-row layout on a 0.100" (2.54 mm) pitch, giving designers a high contact count within a compact PCB footprint compatible with standard hole grids.
What current rating applies to each contact of this SAMTEC terminal strip?
Each contact is gold-plated and rated for 3A of continuous current, enabling the 50-position connector to carry both logic-level signals and moderate power rails simultaneously without exceeding individual pin thermal limits.
Which operating temperature range does the TSM-125-04-SM-DH-A-K-TR support?
The connector is rated for continuous operation from -55°C to 125°C, making it suitable for industrial control systems, outdoor telecom line cards, and military-grade embedded modules where wide thermal excursions are common.
When should a designer choose TSM-125-04-SM-DH-A-K-TR over a lower-position-count alternative?
When a design requires 50 parallel signal or power lines within a single connector footprint, this 50-position strip reduces board space and assembly time compared to using multiple smaller connectors, while still maintaining a standard 2.54 mm pitch compatible with common PCB routing rules.
