Rated 8 A per circuit with gold-plated mating contacts (30.0 µ\" gold) over brass pins, this header handles power-level current for main DC rails or distribution lines — not just signal duty. Termination is SMT solder to the PCB. The board lock features are critical for SMT process reliability — they keep the header seated during reflow and add mechanical retention against cable pull forces after the connector is mated. The 0430451618 carries 18 circuits at the same 3.00 mm pitch and 8 A rating — the only functional difference is the position count. Choose the 16-circuit variant when your BOM calls for exactly 16 positions; the 18-circuit sibling is the next step up for an 18-wire harness.","metaTitle":"Molex Micro-Fit 3.0 0430451617 Header, 16-circuit SMT, 8 A","metaDescription":"Molex 0430451617 Micro-Fit 3.0 header, 16 circuits, 3.00mm pitch, SMT, gold-plated contacts rated 8A, 600V.
