It carries a 3.00 mm pitch, 8 A per circuit current rating, and a 600 V voltage rating — the 8 A per circuit is high for this pitch class, so this is a power interconnect, not a signal line. The header is surface-mount, right-angle, with a shrouded 4-wall housing, a locking ramp for secure mating, and a board lock for SMT retention during reflow. Typical applications include automotive, industrial, medical, and telecommunications equipment where a reliable, vibration-resistant connection is needed. The receptacle accepts crimp terminals for 20-24 AWG wire, making it a wire-to-board interconnect. The SMT solder tails are designed for reflow assembly, and the board lock keeps the header in place during the process.","metaTitle":"Molex Micro-Fit 3.0 430451207, 12-Pos Header, 8A, SMT R/A","metaDescription":"Molex 430451207 Micro-Fit 3.0 header, 12 circuits, dual row, 3.00mm pitch, SMT right-angle, gold contacts, 8A, 600V.
