The Amphenol BERGSTIK II 86840-412HLF is a 12-position, dual-row, unshrouded male pin header on the standard 0.100-inch (2.54 mm) pitch. It is a board-to-board interconnect, right-angle through-hole mounted, with tin-plated phosphor bronze contacts rated at 5 A per circuit and 110 V. The black glass-filled polyester housing carries a UL94 V-0 flammability rating. All 12 positions are loaded.
What the Ratings Mean for the Fit
The 0.100-inch pitch is the breadboard and perfboard standard — this header drops into a 0.100-inch grid layout without board redesign. The 5 A per circuit rating is typical for signal-level and moderate power duty on a tin-plated contact; the limiting factor at this pitch is the temperature rise of the housing, not the contact itself. The right-angle orientation places the pin axis parallel to the PCB, which suits board-edge or mezzanine-style connections where the mating cable or board enters from the side. The 0.190-inch (4.83 mm) insulation height gives clearance for routing traces under the body on the top layer.
