Frequently Asked Questions
How many positions does the TSM-126-03-SM-DH-A-K-TR provide and how are they arranged?
The TSM-126-03-SM-DH-A-K-TR provides 52 total positions arranged in a dual-row (DH) configuration with 26 contacts per row at 0.100" (2.54 mm) pitch. This high-density layout makes it suitable for applications requiring 52 signal or power connections in a compact SMT footprint.
What contact plating does the TSM-126-03-SM-DH-A-K-TR use and why does it matter for signal integrity?
The -K suffix indicates gold-plated contacts, which provide contact resistance below 20 mΩ and excellent corrosion resistance over extended service life. Gold plating ensures stable signal integrity for low-level analog signals and high-speed digital interfaces across 52 positions, making it suitable for precision instrumentation and communications equipment.
Which assembly processes are compatible with the TSM-126-03-SM-DH-A-K-TR surface mount terminal strip?
The TSM-126-03-SM-DH-A-K-TR is designed for surface mount reflow soldering processes, compatible with standard solder paste application and reflow ovens operating at peak temperatures up to 260°C. The tape-and-reel (-TR) packaging supports automated pick-and-place machines, enabling consistent placement accuracy across all 52 positions in high-volume production.
When should a designer choose the 52-position TSM-126-03-SM-DH-A-K-TR over a lower-count connector?
When a design requires 52 or more signal connections between PCBs at 2.54 mm pitch, the TSM-126-03-SM-DH-A-K-TR eliminates the need for multiple smaller connectors, reducing BOM count and assembly complexity. It is particularly advantageous in backplane and daughter card designs where consolidated connector count saves routing space and lowers total interconnect cost per signal.
