The Molex 430451011 is a 10-position dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power and signal interconnects. It uses a 3.00mm pitch, right-angle SMT mounting with solder retention features, and a 4-wall shrouded housing with a locking ramp for secure mating. Rated 8A per circuit at 600V, it carries gold-plated mating contacts (30.0µin) over a tin-plated post, and the glass-filled LCP housing meets UL94 V-0. Typical applications include automotive, industrial, medical, and telecom harness assemblies where vibration resistance and a positive lock are required.
The locking ramp fastening means this header stays mated under vibration — it's not a friction-only fit, so the mating receptacle needs the matching ramp feature.
