It carries a 3.00 mm row spacing, 8 A per circuit current rating, and a 600 V voltage rating, with tin-plated mating contacts at 60.0 µin thickness. The shrouded 4-wall design with a locking ramp and integrated board lock provides mechanical retention for vibration-prone environments like automotive, industrial, medical, and telecommunications equipment. ## What the Ratings Mean for Your Fit The 8 A per circuit rating at 600 V is well above signal-level requirements — this header is sized for moderate power distribution within a harness, not just low-current logic. The tin mating finish at 60.0 µin is a robust industrial-grade plating; it handles repeated mating cycles in controlled environments but is not optimized for extreme corrosion resistance or thousands of cycles like gold would be. The locking ramp audibly confirms full engagement, and the board lock secures the header to the PCB during soldering and under cable strain — both features matter when the assembly sees vibration in an automotive or industrial cabinet. ## Mating and Termination This header mates with the corresponding Micro-Fit 3.0 receptacle housing (sold separately) that accepts crimp terminals for 20–24 AWG wire. The through-hole termination with kinked solder tails provides a reliable mechanical and electrical connection to the PCB. The 0.125\" post length suits standard board thicknesses.","metaTitle":"Molex Micro-Fit 3.0 430450224 Header, 2 Pos, 8 A, 600 V","metaDescription":"Molex Micro-Fit 3.0 430450224 vertical header, 2 positions, 2 rows, 3.00 mm pitch, 8 A, 600 V, tin plating, shrouded, locking ramp.
