BC548 - TO92 NPN Transistor
BC548 is a general-purpose NPN bipolar junction transistor widely used in electronic devices. It is the first type of bipolar transistor encountered specifically by hobbyists and is often featured in designs in hobby electronics magazines where a general-purpose transistor is required. The BC548 is low cost and widely available.
