For a board-to-board header that mates once during assembly and stays put, this is a cost-effective choice.","metaTitle":"FCI 87900-446HLF BERGSTIK II Header, 46-Pos 0.100\" Pitch","metaDescription":"FCI 87900-446HLF BERGSTIK® II unshrouded header, 46 positions, dual-row 0.100\" pitch, tin-plated contacts rated 5 A.
