It carries 8 A per circuit at 600 V on a 3.00 mm pitch, with a shrouded 4-wall housing and a locking ramp for positive retention in mated assemblies. The tin-plated mating contacts (100.0 µin) and through-hole kinked-pin termination suit it for automotive, industrial, medical, and telecom harness applications where vibration resistance and a UL94 V-0 flame rating are required.","metaTitle":"Molex 430451212 Micro-Fit 3.0 Header, 12 Pos, 8A","metaDescription":"Molex 430451212 Micro-Fit 3.0 header, 12-circuit dual-row, 3.00mm pitch, through hole, tin-plated, 8A, 600V, shrouded with locking ramp.
