The 75160-118-03LF is a 3-position unshrouded male pin header from the FCI BERGSTIK® series, arranged in a single row on a 0.100" (2.54 mm) pitch. The black thermoplastic housing is rated UL94 V-0. Typical use cases include low-to-moderate current board-to-board signal or power distribution where the exposed pin row gives visual access for test clips or manual wiring.
The 0.100" (2.54 mm) pitch is the standard legacy spacing — any board footprint designed for a 2.54 mm pin header accepts this part, but the 3-position count is the BOM line gate. The 0.225" (5.72 mm) mating pin length gives enough engagement depth for standard 0.100" pitch receptacles without bottoming out.
