It's a Board to Cable/Wire interconnect — the male pins mate with Micro-Fit 3.0 receptacle housings carrying crimped terminals. The locking ramp fastening type gives positive retention in high-vibration environments like automotive or industrial machinery. The 600 V rating gives enough creepage headroom for industrial and telecom bus voltages. The 3.00 mm pitch is the board-layout anchor: your PCB footprint must match this exactly, and the dual-row arrangement means the row spacing is also 3.00 mm, so the total footprint is a 2x5 grid on that pitch. Gold on the mating side (15.0 µ in) vs tin on the solder tail (100.0 µ in) is the right split — the gold handles the mating cycles, the thick tin gives a reliable solder joint to the board. UL94 V-0 housing means this header is accepted inside equipment enclosures that require flame-rated components.","metaTitle":"Molex Micro-Fit 3.0 430451019 Header, 10 Pos, 3mm, SMT, 8A","metaDescription":"Molex 430451019 Micro-Fit 3.0 SMT header, 10 circuits, dual-row 3.00mm pitch, 8A, 600V, gold mating contacts.
