It uses a 3.00 mm pitch, which sets the board footprint spacing, and carries an 8 A per circuit current rating with a 600 V voltage rating — enough headroom for distribution-level power inside an enclosure. The through-hole mounting with kinked solder tails gives a solid mechanical anchor on the PCB, and the 4-wall shrouding protects the male pins during handling and mating. This header is specified for automotive, industrial, medical, and telecom applications where the locking ramp provides positive retention against vibration and the UL94 V-0 rated LCP housing meets the flammability requirements for equipment inside an enclosure. The operating temperature range of -40°C to 105°C covers under-hood and industrial cabinet environments. ## Key Ratings and What They Mean for Fit The 3.00 mm pitch and 0.118\" row spacing define the PCB layout — the same pitch as the mating receptacle, so the footprint is standard for the Micro-Fit 3.0 family. The 8 A per circuit rating is the current each pin can carry continuously at room temperature; for elevated ambient conditions, derate per the manufacturer's curve. The 600 V rating is the maximum working voltage between adjacent circuits, limited by the creepage distance the 3.00 mm pitch provides. The tin-plated mating contacts with 60.0 µin (1.52 µm) thickness are suited for moderate mating-cycle applications — tin is cost-effective for permanent or infrequent connections, while gold would be specified for high-cycle or corrosive environments. The board lock feature holds the header in place during wave soldering and resists shear forces from cable strain. ## Mating and Termination This header mates with the Micro-Fit 3.0 receptacle housings (e.g., 43025 series) using the matching crimp terminals. The locking ramp engages with the receptacle latch for audible, positive retention — no secondary lock needed for most applications. The through-hole termination with kinked pins provides a secure solder joint that withstands the insertion force of the mating cycle.","metaTitle":"Molex Micro-Fit 3.0 0430451424 Header, 14 Pos, 3.00mm Pitch","metaDescription":"Molex Micro-Fit 3.0 0430451424 header, 14 circuits, 3.00mm pitch, 8A, 600V, through-hole, locking ramp.
