  • Overview

    The features of small outline package (SOP) are similar to SOJ, except that the leads' end is formed in the shape of a gull-wing. SSOP is the shrunk version of SOP, with lead pitch narrowed from 1.27mm (50mil) to 0.635mm (25mil). The shrunk body means flexible layout within finite PCB area. Another advantage is that shorter leads improve the electrical performance.

    Application
