Rated 8 A per circuit at 600 V, with tin-plated mating contacts at 60.0 µin thickness, this header is built for cost-sensitive, moderate-cycle power interconnects in automotive, industrial, medical, and telecom equipment. The 8 A per-circuit rating is solid for a 3.00 mm-pitch power header — the limiting factor is the tin-plated contact finish, which handles fewer mating cycles than gold but keeps the per-unit cost down for applications where the connector is mated once or a few times in the field. The 600 V rating gives enough creepage margin for the pitch class, so the voltage limit won't constrain a typical 24 V or 48 V power bus. This header mates with the matching Micro-Fit 3.0 receptacle housing (e.g., the 43025 series) and accepts the crimp terminals that terminate 20-24 AWG wire. The dual-row, 8-position layout with 0.118\" row spacing means the mating receptacle must be a dual-row, 8-circuit part with the same pitch — verify the position count and row configuration against the BOM before ordering. Termination is through-hole solder — the 0.125\" (3.18 mm) post length is sized for standard PCB thicknesses around 1.6 mm.","metaTitle":"Molex Micro-Fit 3.0 430450821, 8 Pos Header, 3mm Pitch","metaDescription":"Molex 430450821 Micro-Fit 3.0 header, 8 circuits, 2 rows, 3.00mm pitch, right-angle, through-hole, tin contacts, 8A, 600V, board lock.
