The Amphenol BERGSTIK® II 78511-136HLF is a 36-position, single-row, unshrouded male pin header on 0.100" (2.54 mm) pitch — a standard footprint that matches legacy breadboard layouts and common IDC ribbon cable receptacles. Rated 5 A per contact with 30.0 µ" (0.76 µm) gold plating on the mating surface, it is sized for signal-level interconnect and repeated mating cycles in controlled environments, not bus-level power distribution. The unshrouded push-pull design means retention relies on the mating housing's latch — appropriate for internal wire-to-board harnesses where the assembly is not subject to high vibration or cable strain.
Position count and footprint
At 36 positions loaded on a single row, this header occupies approximately 3.6 inches (91.4 mm) of board edge — a significant footprint that requires the mating receptacle to have the same position count and pitch. The 0.100" pitch is shared across the BERGSTIK® II family, so a 3-position sibling like the 68024-103HLF uses the same contact spacing but a much shorter body; the selection decision is purely the circuit count matching the BOM.
The 5 A per-contact rating at the stated temperature is typical for signal circuits; derating is expected above 25°C ambient per the manufacturer's derating curve.
