Frequently Asked Questions
How many positions and what pitch does TSM-135-03-SS-DH-A-K-TR provide?
TSM-135-03-SS-DH-A-K-TR is a 70-position dual-row terminal strip with a 0.100" (2.54 mm) pitch, giving designers 70 pins for signal and power routing on a standard SMT footprint.
Can TSM-135-03-SS-DH-A-K-TR be placed by automated SMT pick-and-place equipment?
Yes. The TR suffix indicates tape and reel packaging, and the surface mount termination style is fully compatible with automated pick-and-place and standard reflow soldering at temperatures up to 260°C.
What contact finish is used on TSM-135-03-SS-DH-A-K-TR and why does it matter for connector reliability?
The mating contacts use gold plating over a nickel barrier layer, which provides low contact resistance and excellent corrosion resistance, making these 70 pins suitable for high-cycle industrial and test applications.
Is TSM-135-03-SS-DH-A-K-TR compliant with RoHS and lead-free assembly requirements?
TSM-135-03-SS-DH-A-K-TR is RoHS-compliant and lead-free, making it suitable for products targeting EU and global markets that require halogen-free and Pb-free construction across all 70 contact positions.
