The Amphenol 68653-103HLF is a 3-position unshrouded male pin header from the BERGSTIK II series, on a 0.100" (2.54 mm) pitch in a single row. The mating contacts carry 30.0 µin (0.76 µm) gold plating over phosphor bronze, and the black housing is rated UL94 V-0. This is the 3-circuit member of a standard-density pin header family used for board stacking and wire-to-board connections where a low-profile, unshrouded interface is acceptable.
The 0.100" pitch is the industry-standard 0.100 x 0.100 inch grid — the footprint matches any standard 0.100" header layout, so board routing and keep-out zones are predictable. 5 A per circuit at 110 V is typical for signal-level and low-power duty; the limiting factor is the pin density and the unshrouded design, not the contact itself.
As an unshrouded header, this part is typically used as the board-mounted half of a wire-to-board or board-to-board interconnect where the mating receptacle or female header slides over the pins. The push-pull fastening and lack of a shroud mean it is best suited for internal, low-vibration environments — think test equipment, control boards, or peripheral I/O where the connector is not subject to heavy cable strain.
