It sits as the 22-circuit SMT variant in a family that spans 2 to 24 positions at the same 3.00 mm pitch, all sharing the same shrouded 4-wall housing and locking ramp. The locking ramp fastening type is the key mechanical differentiator for automotive/industrial use where the mated pair must resist unplugging under shock or vibration. The 22-position dual-row layout accepts the standard Micro-Fit 3.0 crimp terminals (20-24 AWG) in the receptacle side.","metaTitle":"Molex Micro-Fit 3.0 430452219, 22-Pos Header, 3mm Pitch, SMT","metaDescription":"Molex 430452219 Micro-Fit 3.0 header, 22-position dual-row, 3.00mm pitch, SMT, gold-plated contacts, rated 8A at 600V.
