22-Circuit Micro-Fit 3.0 Power Header with Board Lock
The Molex 0430452206 is a 22-position, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power interconnects.
The 8 A per circuit rating at 600 V is the headline power spec — this is a power-grade interconnect, not a signal-only header, and the 3.00 mm pitch provides enough creepage for the 600 V rating without forcing an oversized board footprint.
This header is listed for use in automotive, general-purpose, industrial, medical, and telecommunications applications. The -40 to 105 °C operating range and UL94 V-0 LCP housing confirm suitability for under-hood automotive compartments and industrial enclosures that require flame-rated materials. The board lock and locking ramp together handle vibration and shock typical of engine compartments and moving machinery.
Termination is SMT solder to the PCB; the board lock provides additional mechanical hold during reflow and in service.
