The 8 A per circuit rating means each pin can carry moderate power — sized for a DC rail or multiple signal lines, not a single high-current bus. Board locks on the housing add shear-force resistance against cable strain, which is useful when the mating receptacle is part of a harness that gets flexed. The insulation height of 0.390\" (9.91 mm) and post length of 0.125\" (3.18 mm) set the z-height budget for the mated pair.","metaTitle":"Molex Micro-Fit 3.0 430451225, 12 Pos Header, 3mm Pitch, 8A","metaDescription":"Molex Micro-Fit 3.0 header 430451225, 12 circuits dual-row, 3.00 mm pitch, 8 A per circuit, gold plating.
