BC548

The BC548 is a general-purpose NPN bipolar junction transistor commonly used in European and American electronic equipment. Notably, it is often the first type of bipolar transistor hobbyists encounter and is often featured in designs in hobby electronics magazines where a general-purpose transistor is required. The BC548 is low in cost and widely available.
