Header for Board-to-Wire Power Distribution
The Molex 430452007 is a 20-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power interconnects in automotive, industrial, medical, and telecom equipment. It mates with the standard Micro-Fit 3.0 receptacle housing using the matching crimp terminal — the locking ramp and shrouded 4-wall design prevent mis-mating and keep the connection secure under vibration.
Gold on the mating side at 15.0 µ" (0.38 µm) handles repeated mating cycles without oxidation creep — the Micro-Fit 3.0 series is rated for 50-plus cycles, so this header suits applications where the harness is disconnected for service or rework. The 600 V rating and UL94 V-0 LCP housing mean it passes the flame rating required inside an equipment enclosure, and the -40°C to 105°C operating range covers under-hood automotive and industrial cabinet environments.
