Board-to-Wire Power Header for High-Density Harnesses
The Molex 430451623 is a 16-circuit, dual-row right-angle header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power distribution. The 3.00 mm pitch and 8 A per circuit rating place it in the power interconnect class, not signal-level, so the wire gauge and trace width on the PCB need to be sized accordingly.
Key Features for the Build and the Board
Gold plating on the mating contacts (30.0 µin) supports repeated mating cycles in corrosive or humid environments, while the tin-plated solder tails (100.0 µin) are standard for reliable through-hole soldering. The UL94 V-0 LCP insulator handles the -40°C to 105°C operating range without issue.
