Rated 8 A per circuit at 600 V on a 3.00 mm pitch, it carries enough headroom for mid-range power distribution in automotive, industrial, medical, and telecom harness assemblies. The shrouded 4-wall housing with a locking ramp and board locks provides positive retention against vibration; the 60.0 µin tin plating on the mating surface is suited for moderate mating-cycle duty in controlled environments. ## Mating & Termination Mates with the matching Micro-Fit 3.0 receptacle housing (sold separately).","metaTitle":"Molex Micro-Fit 3.0 430451224 Header, 12 Pos, 3mm, 8A, 600V","metaDescription":"Molex 430451224 Micro-Fit 3.0 vertical header, 12 circuits, 2 rows, 3.00mm pitch, 8A per circuit, 600V, UL94 V-0.
