The Amphenol BERGSTIK® 75160-150-03LF is a 3-position, single-row, unshrouded board-to-board header on the standard 0.100" (2.54 mm) pitch.
The 0.100" (2.54 mm) pitch is the de facto standard for breadboard-compatible headers — any board laid out for a 0.100" grid accepts this part without a footprint change. The 3 positions mean this is a low-circuit-count interconnect, typically used for a single signal/power jumper, a programming header, or a sensor interface.
The 75160-150-03LF is the 3-position member of the BERGSTIK® unshrouded header family. The base product number 75160 covers single-row, 0.100" pitch headers with various position counts and plating options. Compared to a tin-plated sibling in the same family, the gold variant adds cost but eliminates the risk of fretting corrosion in low-current or high-vibration environments.
