It carries a 3.00 mm pitch on both the mating interface and row spacing, which sets the PCB footprint — the 0.118\" (3.00 mm) centers give enough room for routing a 600 V rated trace between pads without forcing an oversized board. The 8 A per contact rating means this header handles real power, not just signal; the 600 V voltage rating backs that up for industrial and telecom bus applications. Applications include automotive, general purpose, industrial, medical, and telecommunications equipment — the UL94 V-0 LCP housing and -40°C to 105°C operating range suit it for enclosed equipment and moderate-temperature environments. The shrouded 4-wall design with a locking ramp fastening type means this header mates positively with the matching Micro-Fit 3.0 receptacle housing — the ramp locks audibly and resists vibration unseating in automotive or industrial machinery. The through-hole termination with kinked pins provides mechanical retention through the solder wave; the 0.125\" (3.18 mm) post length suits standard PCB thicknesses. Contact finish is 100.0 µin (2.54 µm) tin on the mating side and tin on the post — the heavy tin plating supports repeated mating cycles in power applications where gold would be overkill, though it does not match the cycle life of a gold-plated contact.","metaTitle":"Molex Micro-Fit 3.0 0430451412 Header, 14 Circuits","metaDescription":"Molex 0430451412 Micro-Fit 3.0 header, 14 positions, 2 rows, 3.00mm pitch, 8A, 600V, through-hole, shrouded, locking ramp.
