The Amphenol FCI 79425-436HLF is a 36-circuit, dual-row unshrouded header from the BERGSTIK® II series, built on the industry-standard 0.100" (2.54mm) pitch. It carries 5 A per circuit at 110 V, with tin-plated phosphor bronze contacts on both the mating surface and solder tails — the 100.0 µin (2.54 µm) tin finish on the mating side is suited for moderate-cycle applications where cost per position is a factor.
What the 5 A rating means for this header
5 A per circuit is the headline current at the rated temperature rise — this is a signal-to-light-power header, not a bus-bar interconnect. For a 36-position board-to-board link carrying logic-level signals and the occasional low-power rail, this rating gives comfortable margin. The 110 V rating is the working voltage; the actual creepage distance between adjacent pins at 0.100" pitch supports that voltage in dry indoor environments.
The unshrouded pins (0.190" / 4.83 mm mating length) require the mating half to provide the alignment and polarization; there is no shroud to prevent off-angle insertion. On the board side, the 0.120" (3.05 mm) post length and 0.100" (2.54 mm) insulation height set the standoff above the PCB. The through-hole footprint is the standard 0.100" x 0.100" grid with 0.025" square pins — a layout any PCB tool generates from the 36-position, 2-row pattern. The overall contact length of 0.410" (10.41 mm) gives the pin enough body to pass through a standard 0.062" board and still leave a clean solder fillet.
This is a standard-catalog BERGSTIK II part, not a special or phased variant.
