The Amphenol FCI BERGSTIK II 87901-104HLF is a 4-circuit, dual-row unshrouded header on a standard 0.100" (2.54 mm) pitch, designed for board-to-board interconnect. It carries 5 A per contact with 30.0 µ" gold plating on the mating surface over phosphor bronze — the gold thickness supports repeated mating cycles, while the 5 A rating is typical for signal-level duty on a 0.100" pitch. The through-hole termination and 0.100" (2.54 mm) row spacing land on a familiar 0.100" grid footprint, making it a drop-in for prototyping or production where an unshrouded, push-pull header is called for. The black housing is rated UL94 V-0.
Within the BERGSTIK II series, the 87901-104HLF is the 4-position member.
