The Molex 0430450223 is a 2-circuit member of the Micro-Fit 3.0 43045 series, a shrouded 4-wall header designed for board-to-cable/wire interconnect. It carries 2 positions loaded across 2 rows at a 3.00 mm pitch, rated 8 A per circuit at 600 V with gold-plated mating contacts (30.0 µin) for reliable signal and low-power duty in automotive, industrial, medical, and telecom environments.
The 3.00 mm pitch and 2-position count are the first fit check: this header matches a 2-circuit BOM line on a 0.118-inch grid. The 8 A per circuit at 600 V is genuine power capability — the 30.0 µin gold on the mating side handles repeated mating cycles without oxidation, while the 100.0 µin tin on the solder tail gives a reliable through-hole joint.
The header is supplied in tray packaging.
