Micro-Fit 3.0 43045 right-angle SMT header
The Molex 430451007 is a 10-position dual-row male header in the Micro-Fit 3.0 43045 series, configured for right-angle surface-mount board-to-cable interconnects. The 3.00 mm pitch and dual-beam contact geometry give it a current rating of 8 A per circuit at up to 600 V — a rating that reflects the Micro-Fit 3.0 series' primary position in harnesses and board assemblies where space-constrained power delivery is a constraint. The mating face carries 15.0 µin (0.38 µm) gold over brass, while the solder tail is tin-plated at 100.0 µin (2.54 µm) to survive multiple reflow cycles without solderability loss. Four-wall shrouding and the locking ramp fastening type keep the mating half secured in high-vibration environments — the board lock on the header heel adds side-load retention at the PCB interface, which matters in automotive and industrial harnesses where the connector is seated before the cover closes. The insulation body is black glass-filled liquid crystal polymer rated UL94 V-0, spanning an operating window of -40°C to 105°C. Packaging is Tape & Reel or Cut Tape to suit pick-and-place or hand-assembly workflows.
Where the 10-circuit member sits in the 43045 series
The 430451007 carries the same 3.00 mm pitch, dual-row footprint, and SMT right-angle profile as every other member of the Micro-Fit 3.0 43045 header family — the circuit count is what scales across the series. At 10 positions the 430451007 falls in the mid-range of the family, offering enough circuits for multi-circuit power rails or signal bundles where the 8 A per-contact rating is the primary selection driver over a smaller-position sibling. The board lock is listed as a feature on this member, which is consistent with the right-angle SMT variant providing mechanical retention at the PCB heel — confirm the board lock is compatible with your pad geometry if your layout uses non-standard paste or pad sizing.
