12-circuit shrouded header with board lock
The 0430451201 is the 12-circuit member of Molex's Micro-Fit 3.0 43045 header line, a shrouded 4-wall board-to-wire header with a locking ramp for positive retention. It carries gold-plated mating contacts rated 600V and mounts through-hole right-angle with a board lock for SMT reflow retention and vibration resistance.
Pitch, rows, and board footprint
The 12 positions are fully loaded; the shrouded 4-wall housing with locking ramp prevents mis-mating and holds the pair against vibration.
