The 8 A per circuit rating and 600 V voltage rating place it in the mid-power range for this series, suited for applications like automotive, industrial control, and telecom equipment. ## What the Key Specs Mean for Fit The 3.00 mm pitch is the standard for the Micro-Fit 3.0 family, giving enough creepage for the 600 V rating without forcing an oversized board footprint. The 8 A per circuit is a per-contact limit at a given temperature rise; the actual current you can run depends on how many circuits are loaded simultaneously and the ambient temperature up to the 105 °C ceiling. It mates with the standard Micro-Fit 3.0 receptacle housings that use the matching crimp terminals.","metaTitle":"Molex Micro-Fit 3.0 430451607 Header, 16 Pos, 3mm, 8A","metaDescription":"Molex Micro-Fit 3.0 430451607 SMT header, 16 circuits, 3.00mm pitch, 8A, 600V, gold plating.
