Rated 8 A per circuit at 600 V, this header handles moderate power distribution — the 3.00 mm pitch provides enough creepage for the 600 V rating without an oversized board footprint. The gold-plated mating contacts (30.0 µ\" / 0.76 µm) are suited for repeated mating cycles and corrosive environments, while the tin-plated solder tails (100.0 µ\" / 2.54 µm) provide a reliable through-hole solder joint. The dual-row footprint at 3.00 mm row spacing matches the standard Micro-Fit 3.0 layout, so board layout is consistent across the series.","metaTitle":"Molex Micro-Fit 3.0 0430452029 Header, 20 Circuits, 8 A","metaDescription":"Molex 0430452029 Micro-Fit 3.0 header, 20 positions, 3.00 mm pitch, 8 A per circuit, gold-plated contacts.
