It uses a 0.118 in (3.00 mm) pitch, giving enough creepage for the 600 V rating without forcing an oversized board footprint. Rated 8 A per circuit at 600 V, the 8 A figure is the per-contact limit at a 30 °C temperature rise — the dual-row layout shares the return path across both rows, so the total power through the header sums across all four circuits. Tin-plated mating contacts (60.0 µin / 1.52 µm thickness) are suited for moderate mating-cycle duty in automotive, industrial, or telecom equipment where the connector is mated a few times over its life and the application environment is not aggressively corrosive. The shrouded 4-wall housing with locking ramp prevents mis-mating and gives a positive audible latch when fully seated. The glass-filled LCP housing carries a UL94 V-0 flammability rating and operates from -40 °C to 105 °C, covering the thermal range inside an equipment enclosure or underhood automotive interior.","metaTitle":"Molex Micro-Fit 3.0 430450406, 4-Pin Right-Angle SMT Header","metaDescription":"Molex 430450406 Micro-Fit 3.0 header, 4 circuits, 3.00 mm pitch, right-angle SMT with board lock, 8 A, 600 V, tin-plated contacts.
