It carries 8 A per circuit at 600 V, with a 3.00 mm pitch that balances current density against board-space efficiency — enough creepage for the voltage rating without blowing up the footprint. The 8 A per circuit rating is the headline number, but it's derated above 25 °C ambient — the LCP housing is rated UL94 V-0 and handles the temperature rise, but pack the circuits at full load in a hot enclosure and you'll want to check the derating curve. The 3.00 mm pitch and row spacing set the board footprint: 0.118\" centers, which is standard for this class of connector. The 30.0 µin gold on the mating side is the real differentiator — it's what lets this header survive 50+ mating cycles in a field-serviceable assembly without contact fretting. Tin contacts would gall and oxidize under the same duty. This header mates with any standard Micro-Fit 3.0 receptacle housing that carries the matching 14-circuit, dual-row layout — the locking ramp engages the receptacle latch for a positive lock.","metaTitle":"Molex Micro-Fit 3.0 430451414 Header, 14 Pos, 3mm, 8A","metaDescription":"Molex 430451414 Micro-Fit 3.0 header, 14 circuits, 2 rows, 3.00mm pitch, 8A, 600V, gold mating contacts, shrouded.
