The contacts are male square pins in phosphor bronze with a 100.0µin (2.54µm) tin finish on the mating surface and tin on the solder tails — a thick tin layer suited for occasional mating cycles in a permanent or semi-permanent board-to-board interconnect, not a high-cycle reconnection duty. The 5 A per-contact rating is typical for a signal-level header at this pitch — the limiting factor is the 0.100\" pin spacing and the tin interface, not the contact cross-section. For power distribution above a couple of amps per circuit, you'd want a thicker pin or a shrouded header with a higher current rating. The through-hole termination gives a solid mechanical anchor on the board, and the 0.120\" (3.05mm) post length fits standard 0.062\" to 0.093\" PCBs without bottoming out. It is RoHS compliant.","metaTitle":"FCI 78511-407HLF BERGSTIK II Header, 7 Pos 2.54mm, 5A","metaDescription":"FCI BERGSTIK® II 78511-407HLF unshrouded header, 7 positions, 0.100\" pitch, tin-plated contacts, rated 5A.

The HLF uses a 100.0µin tin mating finish; the SLF uses a gold flash over tin.
