It uses a 3.00 mm pitch, which provides enough creepage distance to support the 600 V rating without forcing an oversized board footprint. The 8 A per-circuit rating is the headline number, but the contact finish — 100.0 µin of tin on the mating surface — is what actually governs the duty. The -40°C to 105°C operating range and UL94 V-0 rated LCP housing mean this header can sit inside an automotive ECU or an industrial controller without concern for thermal or flame compliance. ## How it compares within the series Against the 12-circuit member of the same Micro-Fit 3.0 family (430451210), the 430452412 doubles the position count at the same 3.00 mm pitch and 8 A per-circuit rating. The decision between them is purely a circuit-count match to the BOM — the footprint, mating half, and current headroom are identical.","metaTitle":"Molex Micro-Fit 3.0 430452412, 24-Pin Header, 3mm Pitch","metaDescription":"Molex 430452412 Micro-Fit 3.0 header, 24 positions, 3.00mm pitch, 8A, 600V, tin-plated, through-hole, UL94 V-0.
