The Molex 430450611 is a 6-circuit member of the Micro-Fit 3.0 43045 series, a board-to-cable/wire header designed for power distribution in automotive, industrial, medical, and telecom assemblies. This dual-row, surface-mount right-angle connector sits on a 3.00mm pitch with an identical 3.00mm row spacing, so the board footprint matches the standard Micro-Fit 3.0 receptacle pattern. Each male pin is rated for 8A at 600V, with gold on the mating surface (30.0µin) and a thick tin post (100.0µin) for the solder joint.
The 8A per-circuit rating is the current each pin can carry continuously at room temperature — derate above 25°C per the Micro-Fit 3.0 derating curve. For a 6-position connector carrying power on all circuits, the total current through the header is 48A, but the limiting factor is often the PCB trace width and the mating terminal's wire gauge (20-24 AWG typical). The 600V voltage rating gives enough creepage margin for most low-voltage DC rails and 240VAC industrial control panels.
Placement in the series
Within the Micro-Fit 3.0 43045 family, the 430450611 is the 6-position, dual-row, SMT right-angle variant. Compared to the 12-position 430451210 at the same 3.00mm pitch, this part halves the circuit count — choose the 6-position when the BOM calls for a compact power interconnect with fewer lines, or step up to the 12-position for additional circuits without changing the footprint pitch.
