Micro-Fit 3.0 SMT Header for Wire-to-Board Power
The Molex 430450615 is a 6-position, dual-row surface-mount header from the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire power interconnects.
The 8 A per-circuit rating is the headline number, but the real limit in an SMT header is the solder-joint temperature rise — the contact itself can carry more. The 4-wall shrouding and locking ramp protect against mis-mating and vibration loosening, which matters in automotive and industrial enclosures where the harness sees movement. The UL94 V-0 LCP housing handles the 105 °C operating ceiling without creep, so the connector can sit inside a sealed cabinet next to a power supply without a secondary flame barrier.
