Transistor Bc557 Wikipedia

The denomination 557 bc for this year has been used since the early medieval period when the anno domini calendar era became the prevalent method in europe for naming years. It is notably 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.
