It carries 18 male pin contacts on a 3.00 mm pitch, arranged in two rows with a matching row spacing of 3.00 mm. Rated at 8 A per circuit and 600 V, it handles moderate power loads in a compact footprint. ## Key features and deployment context Contact plating is split by duty: the mating interface carries 30.0 µin (0.76 µm) of gold, rated for repeated mating cycles in corrosive or humid environments; the solder tails are tin-plated (100.0 µin / 2.54 µm) for reliable wave-solder wetting. ## Position count and comparison with the 12-circuit sibling At 18 positions, the 430451802 sits above the 12-circuit 430451210 in the same Micro-Fit 3.0 dual-row header family. Both share the 3.00 mm pitch, 8 A per circuit rating, right-angle orientation, board locks, and gold-plated mating contacts.","metaTitle":"Molex Micro-Fit 3.0 430451802, 18-Pin Right-Angle Header","metaDescription":"Molex 430451802 Micro-Fit 3.0 header, 18 positions dual-row, 3.00 mm pitch, 8 A, 600 V, gold-plated contacts, board lock.
