The header is rated 8A per circuit at 600V, with tin-plated brass contacts — 100.0µin (2.54µm) on the mating finish, tin on the solder post. The 4-wall shrouded housing with a locking ramp and integral board lock provides mechanical retention in high-vibration environments. It operates from -40°C to 105°C, the LCP housing is rated UL94 V-0, and it is ROHS3 compliant. Typical applications include automotive, general purpose, industrial, medical, and telecommunications equipment. The 8A per circuit at 600V rating means each pin can carry moderate power — think a DC motor feed or a solenoid bank, not a signal line. The tin-plated mating contacts are cost-effective for moderate mating cycles; the 100.0µin thickness gives good wear life for field-serviceable harnesses.","metaTitle":"Molex Micro-Fit 3.0 0430451800, 18-Pos R/A Header, 3mm Pitch","metaDescription":"Molex 0430451800 Micro-Fit 3.0 header, 18 circuits, 3.00mm pitch, tin-plated contacts rated 8A at 600V, shrouded with locking ramp.
