It mates with standard Micro-Fit 3.0 receptacle housings for board-to-wire power distribution in automotive, industrial, medical, and telecom equipment. The 0.118\" (3.00mm) pitch and row spacing match the footprint of the series, and the 4-wall shrouding with locking ramp protects contacts and prevents accidental unmating under vibration. Rated 8 A per circuit at 600 V, the 430451023 carries bus-level current for a 3.00 mm pitch header — sized for power rails, not just signal lines. The UL94 V-0 liquid crystal polymer (LCP) housing handles the operating temperature range typical of under-hood and industrial cabinet environments. ## Plating and Duty Cycle Gold on the mating side handles repeated connect/disconnect without oxidation; the thick tin post is for solderability, not cycle life. ## Comparison with 430451024 The 430451023 carries 10 circuits; the sibling 430451024 carries 12 circuits at the same 0.118\" (3.00mm) pitch and dual-row layout. Both share the 8 A per circuit rating, 600 V, gold mating finish, board lock, and locking ramp.","metaTitle":"Molex Micro-Fit 3.0 430451023 Header, 10 Pos, 8A","metaDescription":"Molex 430451023 Micro-Fit 3.0 right-angle header, 10 circuits, 3.00mm pitch, 8A, 600V, gold mating, UL94 V-0.
