quad flatpack

A surface-mount package whose terminals are on four sides and consist of metal pad surfaces (on leadless versions) or leads emerging from the package.

NOTE 1 The package leads may be formed to facilitate surface mounting.

NOTE 2 The small-outline package is similar except for having terminals on only one or two opposite sides of the package.
