The remaining four cavities are empty — the buyer must verify their circuit count against the loaded positions, not the housing size. ## Tin Plating — Cost-Effective for Low-Cycle Mating Both the mating contact finish and the post finish are tin, with a thickness of 80.0 µinch (2.03 µm) on the mating side and 78.7 µinch (2.00 µm) on the post. Tin-on-tin is a reliable, low-cost interface for applications with infrequent mating cycles — think board-to-board within an enclosure that is assembled once.","metaTitle":"77312-483LF BERGSTIK® Header, 12 Pos, 8 Loaded, 2.54mm Pitch","metaDescription":"Amphenol ICC (FCI) 77312-483LF BERGSTIK® board-to-board header, 12 positions (8 loaded), 0.100\" pitch, 3 A per contact, tin plating.
