A reference designator is a component label on a schematic diagram to identify and differentiate between components. It usually consists of a letter indicating the type of component (e.g., "R" for resistor, "C" for capacitor, "D" for diode) followed by a unique number, such as "R1," "C2," or "D3". |

Electronic symbols are graphical representations used to depict electronic components, devices, and circuits in circuit diagrams and schematics. These symbols help engineers, technicians, and hobbyists communicate and understand the design and functionality of electronic circuits. Electronic symbols should be intuitive, allowing users to grasp their meaning at a glance.
Examples of electronic symbols
These symbols are standardized, and various organizations, such as the International Electrotechnical Commission (IEC) and the Institute of Electrical and Electronics Engineers (IEEE), provide guidelines for their use. It's essential to understand these symbols when reading or creating circuit diagrams to design and troubleshoot electronic circuits. The following is a selection of some of the most common symbols.
A reference designator is a component label on a schematic diagram to identify and differentiate between components. It usually consists of a letter indicating the type of component (e.g., "R" for resistor, "C" for capacitor, "D" for diode) followed by a unique number, such as "R1," "C2," or "D3".
