It connects a PCB to a wire harness, mating with the corresponding Micro-Fit 3.0 receptacle housing and crimp terminals. The 3.00 mm pitch and 0.118\" row spacing define the board footprint, while the 8 A per circuit rating at 600 V suits it for moderate-power distribution in automotive, industrial, medical, and telecom equipment. ## Key Features for Assembly and Reliability","metaTitle":"Molex Micro-Fit 3.0 430452421, 24 Pos R/A Header, 3mm Pitch","metaDescription":"Molex 430452421 Micro-Fit 3.0 right-angle header, 24 circuits, 3.00mm pitch, 8A, 600V, tin-plated, locking ramp, board lock, UL94 V-0.
