The Molex 0430452002 is a 20-circuit, dual-row right-angle header from the Micro-Fit 3.0 43045 series. It is a board-to-cable/wire interconnect, designed for applications requiring a reliable, high-current connection in a compact 3.00mm pitch. Key features include a shrouded 4-wall housing for pin protection, a locking ramp for secure mating, and board locks for through-hole retention during soldering.
The 3.00mm pitch and dual-row layout give you a board footprint that balances current capacity with routing density — enough room for 8A per circuit without forcing a wide connector body. The 8A per circuit rating is substantial for a 3mm-pitch header; it means each contact can carry power-level current, not just signal, making this header suitable for DC distribution in harnesses.
The through-hole, right-angle termination requires the PCB to have plated through-holes at the 3.00mm pitch pattern.
