It uses a 3.00mm pitch, giving enough creepage for the 600V rating without forcing an oversized board footprint. The header is shrouded on all four walls with a locking ramp, and includes a board lock for vibration-resistant retention during reflow and in service. It terminates via through-hole kinked pins for solder — the kink holds the part in place during wave solder, a detail that saves rework on the line. ## Key Ratings and What They Mean Rated 8A per circuit at 600V — the 8A figure is the per-contact limit at the rated temperature rise, so a 24-position header can carry up to 192A total if the board and wire harness are sized for it. The 600V rating is line-to-line, not just line-to-ground, which matters for DC bus applications in telecom rectifiers or industrial drives. Tin-plated mating contacts at 60µin thickness are adequate for moderate mating cycles (50-100 mates); if your application needs frequent reconnection, the gold-plated sibling in the same series is the better call. The locking ramp and board lock together mean the header stays put on the PCB under cable strain — no secondary fastener needed. ## Where It's Used Listed for automotive, general purpose, industrial, medical, and telecommunications applications. The -40°C to 105°C operating range and UL94 V-0 housing make it a fit for underhood engine compartments, industrial cabinets, and medical equipment that sees washdown. The 4-wall shrouding protects the pins during handling and prevents bent contacts in harness assembly. ## Mating and Termination This header mates with the Micro-Fit 3.0 receptacle housings using the matching crimp terminals. The locking ramp engages with the receptacle latch for audible confirmation of full mate.","metaTitle":"Molex Micro-Fit 3.0 430452424 Header, 24 Pos, 3mm, 8A","metaDescription":"Molex 430452424 Micro-Fit 3.0 header, 24-position dual-row, 3.00mm pitch, 8A per circuit, 600V, tin-plated contacts, locking ramp, UL94 V-0.
