It carries 8 A per circuit with a 600 V rating, making it a compact power interconnect for board-to-wire applications in automotive, industrial, medical, and telecom equipment. The 3.00 mm pitch gives enough creepage for the 600 V rating without forcing an oversized board footprint — a practical balance for power distribution on dense PCBs. The 8 A per circuit is the headline current, but the 30.0 µ\" gold on the mating side is what governs real duty: it handles the mating cycles and corrosive exposure that tin contacts would fret through. This header mates with the matching Micro-Fit 3.0 receptacle housing (e.g., the 43025 series) using the locking ramp for audible positive retention — a feature that matters in vibration-prone environments like underhood automotive. Termination is surface-mount solder, with the board lock providing additional mechanical hold during reflow. The dual-row 4-circuit layout means two pins per row, which matches the footprint of a 2x2 header.","metaTitle":"Molex Micro-Fit 3.0 430450417, 4-Position SMT Header, 8A","metaDescription":"Molex 430450417 Micro-Fit 3.0 SMT header, 4 circuits, dual row, 3.00mm pitch, gold contacts, 8A, 600V, UL94 V-0.
