It mates with the matching Micro-Fit 3.0 receptacle housing (sold separately) to form a board-to-wire power interconnect. Typical applications span automotive, industrial, medical, and telecom harness assemblies where the locking ramp holds the pair together under vibration. ## Key Ratings and What They Mean Rated 8 A per circuit at 600 V, the 430452229 carries bus-level power through each contact — the 3.00 mm pitch provides enough creepage for the 600 V rating without forcing an oversized board footprint. Gold plating on the mating side (30.0 µin) handles repeated mating cycles and resists corrosion in the automotive and industrial environments the series targets. The UL94 V-0 LCP housing keeps the connector compliant inside enclosed equipment. ## Mounting and Termination Through-hole solder termination with a 0.125\" post length — the header stands 0.390\" off the board. The 4-wall shrouding protects the male pins during handling and guides the receptacle home. A board guide on the housing aligns the part during wave solder, and the locking ramp gives an audible click when fully mated.","metaTitle":"Molex 430452229 Micro-Fit 3.0 Header, 22 Pos, 3mm, 8A","metaDescription":"Molex 430452229 Micro-Fit 3.0 22-position dual-row vertical header, 3.00mm pitch, through-hole solder, gold mating contacts, 8A per circuit, 600V, UL94 V-0.
