El BC548 es un transistor NPN bipolar de propósitos generales utilizado principalmente en equipos de procedencia europea. Eléctricamente es similar al transistor 2N3904 ( estadounidense) y al transistor 2SC1815 ( japonés ), aunque la asignaciones de los pines es distinta. Entre las aplicaciones, se encuentran la de amplificador de ...
