It is a surface-mount, shrouded-4-wall header with a latch holder fastening system, intended for environments where vibration resistance is needed — the latch prevents accidental unmating. ## Contact plating and sourcing posture The insulation height is 0.285\" (7.25mm) — account for this above the PCB when planning component keep-out zones. For a given wire size, consult the Micro-Lock PLUS crimp terminal datasheet for the derated current.","metaTitle":"Molex 5054332081 Micro-Lock PLUS Header, 20 Pos, 1.25mm","metaDescription":"Molex 5054332081 Micro-Lock PLUS header, 20 positions, 1.25mm pitch, SMT, shrouded, latch holder.
