The Molex 430451008 is a 10-position, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire interconnects. It mounts as a surface-mount, right-angle component on the PCB, with a 3.00 mm pitch that balances routing density with the creepage needed for the 600 V rating. The 8 A per circuit rating is per-contact at the stated temperature — useful headroom for power distribution in automotive, industrial, or telecom harnesses where the cable side carries the load. Gold plating on the mating contacts at 30.0 µin (0.76 µm) supports repeated mating cycles without fretting corrosion — a solid choice for field-serviceable connections where the harness gets swapped a few times over the product life.
