The Molex 430451012 is a 10-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire power interconnects. It carries 8 A per circuit at a 3.00 mm pitch, with a 600 V voltage rating backed by the 4-wall shrouding and UL94 V-0 LCP housing. The tin-plated mating surface and kinked solder pins suit it for automotive, industrial, medical, and telecom applications where the locking ramp provides vibration-resistant retention with the matching receptacle housing.
The 600 V rating confirms the LCP housing and 4-wall shroud provide real creepage and clearance for industrial or telecom bus voltages. The locking ramp means the mating receptacle must carry the matching ramp feature — standard Micro-Fit 3.0 receptacle housings do, but it's worth confirming the part number.
