It carries 18 positions (2×9) on a 3.00 mm pitch with a matching 3.00 mm row spacing, rated 8 A per circuit at 600 V. The mating interface is gold-plated at 15.0 µin — enough plating thickness for repeated mating cycles and field service in corrosive environments like automotive or industrial cabinets. The gold-on-mating-side plating (15.0 µin) is the real durability spec: it governs how many mate/unmate cycles the connector can take before the contact resistance drifts, which matters if the assembly sees field service or harness rework. The UL94 V-0 housing means the connector is accepted inside equipment enclosures that require a flame rating. This header mates with the Micro-Fit 3.0 receptacle housings — the ones that accept the 43020-series female crimp terminals (20–24 AWG).","metaTitle":"Molex Micro-Fit 3.0 430451828, 18 Pos Header, 3mm Pitch, 8A","metaDescription":"Molex Micro-Fit 3.0 430451828 dual-row header, 18 positions, 3.00mm pitch, rated 8A at 600V.
