This puts it in the ultra-low-profile class, suited for handheld or compact embedded assemblies where every tenth of a millimeter of z-height is budgeted. The connector uses a plug with outer shroud contacts, meaning the signal contacts are recessed within a plastic shroud that guides alignment during mating and protects the contacts from mechanical damage before assembly. Surface-mount termination and the inclusion of pick-and-place features and solder retention tabs mean this part is designed for automated high-volume assembly. The solder retention features hold the connector in place during reflow, preventing tombstoning or shift on the pad. Confirm the receptacle order code matches the same 18-position, 0.40 mm pitch layout.","metaTitle":"Molex SlimStack 5035521822, 18-Pos Plug, 0.40mm Pitch","metaDescription":"Molex 5035521822 SlimStack plug, 18 positions, 0.40mm pitch, 0.59mm height, gold contacts.
