It serves as the board-mounted half of a board-to-cable/wire interconnect, designed to mate with Micro-Fit 3.0 receptacle housings for power distribution in automotive, industrial, medical, and telecom equipment. The 3.00 mm pitch and 0.118\" row spacing give enough creepage for the 600 V rating while keeping the board footprint compact for a 10-circuit connector. The 8 A per circuit current rating is the starting point for derating at elevated temperatures up to the 105 °C operating limit. The tin finish keeps cost down while the heavy plating layer provides reliable contact wear for the expected mating cycles in a fixed installation. ## Mounting and Retention Details The header sits 0.290\" above the board surface (insulation height). This is a vibration-resistant connection for automotive and industrial environments.","metaTitle":"Molex Micro-Fit 3.0 430451000 Header, 10 Pos, 8A, 600V","metaDescription":"Molex 430451000 Micro-Fit 3.0 right-angle header, 10 circuits, 3.00mm pitch, 8A per circuit at 600V.
