BERGSTIK II Unshrouded Header, 12 Positions
The FCI 68705-412HLF is a 12-position, single-row, unshrouded male header from the BERGSTIK® II series. It uses the standard 0.100" (2.54 mm) pitch that matches breadboard and perfboard layouts, making it a direct fit for many prototyping and production PCB designs. Rated 5 A per contact at 110 V, with tin-plated phosphor bronze contacts, it is suited for internal board-to-board and wire-to-board signal and light-power interconnects where the mating cycle count stays moderate.
Key Specs and What They Mean for Fit
The 0.100" (2.54 mm) pitch is the bread-and-butter spacing for general-purpose PCBs; it gives you room to route traces between pads without squeezing the board layout. The 12 positions are fully loaded, so the BOM circuit count matches the pin count one-to-one. Through-hole solder termination means the header is hand-solderable and rework-friendly, which is a plus for low-volume builds or prototype runs. The 5 A per-contact rating is the practical current ceiling for this header in still air at room temperature. The tin plating (100.0 µin on the mating surface) is a thick, durable finish for moderate-cycle applications — think a few dozen matings over the product life, not daily disconnect. For higher cycle counts, a gold-plated sibling in the BERGSTIK II family would be the better call. The unshrouded design and push-pull fastening mean the header relies on the friction of the mating receptacle for retention. It is not a locking connector, so it is best used in assemblies where the mated pair will not see vibration or cable strain. The UL94 V-0 rated black housing meets the flame-retardancy requirement for equipment installed inside an enclosure.
