It is a board-to-wire interconnect, through-hole mounted with kinked-pin solder tails, designed for power delivery in automotive, industrial, medical, and telecom harness assemblies. The 8 A per circuit rating at 600 V means each contact carries real bus-level current — this is a power-grade header, not a signal interconnect. The UL94 V-0 LCP housing handles the temperature rise from the 8 A load without issue.","metaTitle":"Molex Micro-Fit 3.0 0430450425 Header, 4 Pos, 3 mm Pitch","metaDescription":"Molex 0430450425 Micro-Fit 3.0 header, 4 circuits, dual row, 3.00 mm pitch, through hole, 8 A, 600 V, gold mating contacts, board lock.
