Micro-Fit 3.0 Header, 4 Circuits, Right-Angle Through-Hole
The Molex 0430450422 is a 4-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power and signal interconnects.
The 3.00 mm pitch gives enough creepage for the 600 V rating without forcing an oversized board footprint — it's a standard spacing that matches the Micro-Fit 3.0 receptacle family. Board locks on the through-hole tails add shear-force retention during soldering and against cable strain in service.
