It carries 18 positions on a 3.00 mm pitch with a 3.00 mm row spacing, rated 8 A per circuit at 600 V. The 8 A per circuit rating at the stated operating temperature is the headline current for this header — each tin-plated contact carries that current within the temperature rise limit of the UL94 V-0 LCP housing. Tin plating on the mating surface is suited for moderate mating-cycle applications; the 60.0 µin (1.52 µm) thickness provides good durability for field-service connections without the cost of gold. The 600 V rating, combined with the 3.00 mm pitch and 4-wall shroud, gives enough creepage for equipment-level power distribution inside an enclosure.","metaTitle":"Molex Micro-Fit 3.0 430451827, 18 Pos Header, 3mm Pitch, 8A","metaDescription":"Molex 430451827 Micro-Fit 3.0 male header, 18 circuits, dual-row, 3.00mm pitch, 8A per circuit, 600V, tin-plated, shrouded with locking ramp.
