Micro-Fit 3.0 2-Position SMT Header
The Molex 430450207 is a 2-circuit, 2-row member of the Micro-Fit 3.0 43045 series, configured as a board-to-cable/wire header. Applications include automotive, general-purpose industrial, medical, and telecom harnesses.
The 8 A per-circuit rating is the current each male pin can carry continuously at the rated temperature rise — sized for moderate power distribution within a harness, not just signal-level duty. Gold on the mating side (15.0 µ") versus tin on the post tells you this connector is specced for applications where the mating cycle count is moderate — think field-serviceable automotive modules or medical device interconnects — not a one-time-crimp-and-forget terminal block. The tin tails are standard for SMT solder joints; the gold mating interface prevents fretting corrosion under vibration. The board lock and locking ramp together mean this header is designed to survive the SMT reflow process and the mechanical loads of a cable harness in a moving assembly. The 4-wall shroud prevents pin stubbing during blind mating, which is a common field failure in right-angle connectors on a board edge.
