All Electronic Components List and Symbols
Electronic components are essential building blocks used in circuits and electronic systems. Some of the most commonly used electronic components are resistors, capacitors, inductors, diodes, LEDs, transistors, crystals, and oscillators.
An electronic component refers to any basic discrete device or physical entity that plays a role in an electronic system by influencing the behavior of electrons or their associated fields. Typically, these components are industrial products offered in a standalone form. It’s important to distinguish them from electrical elements, more abstract concepts representing idealized versions of these components.
