The Molex 430450826 is the 8-position, dual-row member of the Micro-Fit 3.0 43045 series — a shrouded, through-hole male header on 3.00 mm pitch. It carries 8 A per circuit at 600 V, with 30.0 µin gold on the mating side and 100.0 µin tin on the solder post. The 4-wall shroud and locking ramp give it a positive mate with the matching Micro-Fit 3.0 receptacle housing, and the board lock holds it through wave solder. Typical applications span automotive, industrial, medical, and telecom harnesses where the 3.00 mm pitch balances current density with board real estate.
8 A per circuit at 600 V is the headline — the 3.00 mm pitch and 0.118" row spacing give enough creepage for that voltage without forcing an oversized footprint. The tin-plated post (100.0 µin) is standard for solder-joint reliability. The board lock resists shear from cable strain during assembly and in service.
