The header is surface-mount with solder retention features, shrouded on all four walls, and secures with a locking ramp — a combination that handles vibration in automotive, industrial, and telecom equipment enclosures. Rated 8 A per circuit at the 600 V mark, with gold plating on the mating side at 15.0 µin (0.38 µm) thickness. Those two specs together mean it can sit inside an industrial cabinet or an engine bay without the housing softening or feeding a fire.","metaTitle":"Molex Micro-Fit 3.0 0430450419 Header, 4 Pos, 8 A, Gold","metaDescription":"Molex 0430450419 Micro-Fit 3.0 SMT header, 4 circuits, 3.00 mm pitch, 8 A, gold-plated contacts.
