Electronic components are electronic elements used in the creation of electronic devices. They can be used as individual components or as constituent parts of more complex systems.

They are divided into two large groups based on the types of package:

  • DIP components. Special holes are made on the printed circuit board for mounting such components.
  • SMD components. Components for surface-mount technology (SMT) which do not require holes in the printed circuit board and have smaller dimensions.

Some of the main electronic components include:

Resistors are components that limit the flow of current in an electrical circuit. They are used to reduce voltage, regulate current, and decrease noise in electrical circuits.

Capacitors are components that store electric charge. They are used for noise filtering in electric circuits, voltage stabilization, and providing energy storage in electric circuits.


Transistors are electronic components used for amplifying or controlling current in electrical circuits. They are used in many electronic devices such as radios, televisions, and computers.


Diodes are electronic components that allow current to flow in only one direction. They are used to provide protection against voltage surges in electrical circuits and to regulate voltage.

Inductors are components that store energy in a magnetic field. They are used for filtering noise in electrical circuits, stabilizing voltage, and amplifying signals.

Microchips are electronic components that contain several transistors, resistors, and other elements on a small crystal made of semiconductor material. They are used to create complex electronic devices such as computers, mobile phones, and other electronic devices.

Relays are electromechanical devices used to control electrical circuits. They allow electrical circuits to be turned on or off using an electrical signal.

Quartz resonators are electronic components that generate an accurate frequency signal.
