Product Introduction
The Amphenol FCI 87052-426HLF is a 26-position unshrouded male pin header from the BERGSTIK® II series. It uses a dual-row layout on a 0.100" (2.54 mm) pitch, with a matching 0.100" row spacing, making it a standard footprint for board-to-board and wire-to-board interconnect in prototype and production builds. The through-hole solder termination suits wave-solder assembly, and the tin-plated mating finish (100.0 µin) is a cost-effective choice for applications with limited mating cycles.
Key Features and Ratings
Rated at 5 A per circuit at 110 V, this header handles moderate signal-level current and voltage typical of internal board interconnects. The 100.0 µin tin plating on the mating surface provides good corrosion resistance for low-cycle connections, while the phosphor bronze contact material offers reliable spring performance over the connector's service life. The black housing carries a UL94 V-0 flammability rating, meeting the flame-retardant requirement for equipment inside an enclosure.
Board Layout Fit
The 0.100" pitch and 0.100" row spacing are industry-standard for 0.025" square pin headers, so the PCB footprint is well-defined. The overall contact length of 0.990" (25.15 mm) includes a 0.770" (19.56 mm) mating pin and a 0.120" (3.05 mm) solder tail — the tail length is short enough for single-sided boards but may require a thinner board for through-hole clearance on thicker builds. The 0.100" insulation height keeps the header low-profile above the board.
