رؤوس أسنان صف واحد 40-Pin بمسافة 2.54mm

The contact resistance is consistently under 30 milliohms across all 40 pins, which made my wiring project much more reliable than with generic headers. A great find for dense connector builds.

Needed a solid set of header pins for a new breadboard project, and these fit perfectly without any wobble. The 2.54mm pitch is exactly what I needed, and they handled the soldering iron heat without issue.

The pin spacing is spot-on for standard perfboard, and the gold plating made soldering much easier than I expected. Handled a small project with some tight angles, no issues with continuity or resistance.
