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.","metaTitle":"Molex Micro-Fit 3.0 430452007, 20-Circuit Header, 8 A","metaDescription":"Molex 430452007 Micro-Fit 3.0 header, 20 circuits, 3.00 mm pitch, right-angle SMT, gold contacts, 8 A per circuit at 600 V.
