This is a surface-mount, right-angle version with a full 4-wall shroud and a locking ramp, so the mated connector stays put under vibration. For a harness that gets mated once in production and stays, this is the right call. The 12-position 430451206 sits alongside the 6-position 430451206 in the same Micro-Fit 3.0 right-angle SMT family. The decision between them is purely circuit count — same 3.00 mm pitch, same 8 A rating, same board lock and shrouding. Match the position count to your BOM line and the footprint stays the same.","metaTitle":"Molex Micro-Fit 3.0 430451206 Header, 12 Pos, 3mm, SMT R/A","metaDescription":"Molex 430451206 Micro-Fit 3.0 header, 12 circuits, dual-row, 3.00mm pitch, SMT right-angle, 8A, 600V.
