thin super small leadless package (TSSLP)
Thin Super Small Leadless Packages (TSSLP) differ from Thin Small Leadless Packages(TSLP) in that they are even narrower than the latter. As can be seen from the name, they are extremely thin and have an overall height of well under one millimeter (0.3 mm).
Depending on the number of contacts, their package width is only 0.32 mm for two contact pads and only 0.74 mm for eight contact pads, making them only half as wide as comparable TSLPs. The same applies to the overall length, which is 0.62 mm for two contact areas and 1.34 mm for six contact areas. The contact pads are mounted below the package and can be used directly for SMT technology.
