The 8 A per contact at 600 V is the headline power spec — this is a power interconnect, not a signal header. ## Mating and Termination Reality The locking ramp engages audibly, and the 4-wall shroud protects the pins from being bent during blind mating. The board lock is the feature that saves your reflow yield — without it, the part can float on the paste and misalign.","metaTitle":"Molex Micro-Fit 3.0 430451215, 12-Position SMT Header","metaDescription":"Molex 430451215 Micro-Fit 3.0 SMT header, 12 positions, 3.00mm pitch, 8A/600V, shrouded with locking ramp and board lock.
