With 20 positions loaded in a single row, the header occupies about 2.0 inches of board edge. Within the same BERGSTIK base product number 77311, the 20-position variant (77311-118-20LF) differs from the 16-position (77311-118-16LF) only in position count — all other specs (pitch, current, plating, material, lifecycle) are identical.","metaTitle":"77311-118-20LF BERGSTIK Header 20 Pos 2.54mm Pitch","metaDescription":"Amphenol ICC (FCI) BERGSTIK 77311-118-20LF unshrouded header, 20 positions, 0.100\" pitch, 3 A per contact, gold mating finish.
