The Molex 430451607 is a 16-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power and signal interconnects. 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.
