The odd pin count is deliberate — it fits BOM positions that call for exactly 11 circuits without the wasted board area of a dual-row footprint. ## Contact Plating and Current Rating — Signal Duty, Not Power Bus At 3 A per pin in an 11-position header, the total current through the connector is 33 A if all pins are loaded simultaneously — but the derating curve (not provided here) would reduce that at elevated ambient temperatures.","metaTitle":"77311-801-11LF BERGSTIK Header, 11 Pos, 0.100\" Pitch, Gold","metaDescription":"Amphenol ICC (FCI) 77311-801-11LF BERGSTIK unshrouded header, 11 circuits, 0.100\" (2.54 mm) pitch, gold mating finish.
