That pitch sets the board footprint and the mating interface — it mates with Micro-Lock PLUS receptacle housings from the same 505568 series. The 4-wall shroud protects the pins during blind mating and guides the receptacle into alignment. ## Current rating depends on your wire — not a fixed number The current rating is listed as varying by wire gauge. For a given application, the current capacity is set by the wire size chosen for the mating terminal — the header itself does not impose a single ceiling. That covers automotive underhood and industrial cabinet environments where the connector sees both cold start and sustained heat. ## SMT termination with pick-and-place and solder retention This header is surface-mount, supplied in tape and reel for automated assembly. The mated stacking height is 7.4 mm. That is the z-height from the PCB surface to the top of the mated receptacle — important when routing the board inside a tight enclosure.","metaTitle":"Molex 5055680431 Micro-Lock PLUS Header, 1.25mm 4-Pin SMT","metaDescription":"Molex 5055680431 Micro-Lock PLUS 1.25mm pitch, 4-position SMT header.
