Micro-Fit 3.0 Header for Tight Two-Circuit Power Connections
The Molex 0430450208 is a 2-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire power interconnects. It carries 8 A per circuit at a 600 V rating, with the 3.00 mm pitch providing enough creepage for that voltage without an oversized footprint. The header is surface-mount, right-angle, with a shrouded 4-wall design and a locking ramp for positive retention — the latch clicks home when mated with the matching Micro-Fit 3.0 receptacle housing.
Board Lock and SMT Retention
For a right-angle SMT connector, the board lock is what keeps the solder joints intact when the cable is tugged — without it, the joint takes the full load and cracks over time.
