The 3.00 mm pitch and row spacing match the standard Micro-Fit 3.0 receptacle footprint, and the 8 A per-circuit rating with gold-plated mating contacts supports repeated mating cycles in field-serviceable harnesses. ## Mounting and Termination Surface-mount right-angle orientation places the connector at the board edge, parallel to the PCB, saving Z-height in a shallow enclosure. The shrouded 4-wall design protects the pins during handling and guides the receptacle into alignment. Solder retention features hold the part in place during reflow before the solder joints set. The -40°C to 105°C operating range covers under-hood and cabinet environments without derating concerns.","metaTitle":"Molex Micro-Fit 3.0 430451811, 18 Pos Header, 3mm Pitch, 8A","metaDescription":"Molex 430451811 Micro-Fit 3.0 header, 18 circuits, 2 rows, 3.00mm pitch, SMT right-angle, gold contacts, 8A, 600V.
