It is a board-to-cable/wire interconnect, meaning it mounts on a PCB and mates with a receptacle housing terminated to a wire harness. The 0.118\" (3.00mm) pitch gives enough room for the 8A per circuit rating without forcing a wide board footprint, and the dual-row layout keeps the connector compact for its circuit count. Typical applications include automotive, general purpose, industrial, medical, and telecommunications equipment where a reliable, vibration-resistant power connection is needed. Rated 8A per circuit at 600V, this header can handle moderate power distribution on a board. The 8A figure is per contact, so a 20-circuit connector can carry up to 160A total if all circuits are loaded evenly, though in practice the temperature rise across the connector will limit the total. For applications requiring frequent field servicing or a corrosive environment, a gold-plated variant of the Micro-Fit 3.0 series would be a better fit. The UL94 V-0 rated LCP housing ensures the connector will not sustain a flame inside the equipment enclosure.","metaTitle":"Molex Micro-Fit 3.0 430452000 Header, 20-Circuit, 8A","metaDescription":"Molex 430452000 Micro-Fit 3.0 right-angle header, 20 circuits, 3.00mm pitch, 8A, 600V, tin-plated, shrouded, board lock.
