Rated 8 A per circuit and 600 V, this header handles moderate power distribution — think a main DC rail or a multi-circuit power bus inside a control cabinet. The tin-plated solder tails (100.0 µin) are standard for through-hole soldering. The board guide feature aids alignment during assembly. ## Mating and sourcing","metaTitle":"Molex Micro-Fit 3.0 430451428 Header, 14 Pos, 3mm, 8A","metaDescription":"Molex 430451428 Micro-Fit 3.0 header, 14-position dual-row, 3.00mm pitch, through-hole, shrouded, gold contacts, 8A, 600V, UL94 V-0.
