Electronic Components, Parts and Their Function

Electronic components are basic electronic element or electronic parts usually packaged in a discrete form with two or more connecting leads or metallic pads.

Electronic Components are intended to be connected together, usually by soldering to a printed circuit board (PCB), to create an electronic circuit with a particular function (for example an amplifier, radio receiver, oscillator, wireless). Some of the main Electronic Components are: resistor, capacitor, transistor, diode, operational amplifier, resistor array, logic gate etc.

Types of Electronic Components

Electronic Components are of 2 types: Active and Passive Electronic Components.

• Passive electronic components are those that do not have gain or directionality. They are also called Electrical elements or electrical components. e.g. resistors, capacitors, diodes, Inductors.
• Active components are those that have gain or directionality. e.g. transistors, integrated circuits or ICs, logic gates.

Electronic Components and Their Functions

1. Terminals and Connectors: Components to make electrical connection.
2. Resistors: Components used to resist current.
3. Switches: Components that may be made to either conduct (closed) or not (open).
4. Capacitors: Components that store electrical charge in an electrical field.
5. Magnetic or Inductive Components: These are Electrical components that use magnetism.
6. Network Components: Components that use more than 1 type of Passive Component.
7. Piezoelectric devices, crystals, resonators: Passive components that use piezoelectric. effect.
8. Semiconductors: Electronic control components with no moving parts.
9. Diodes: Components that conduct electricity in only one direction.
10. Transistors: A semiconductor device capable of amplification.
11. Integrated Circuits or ICs: A microelectronic computer electronic circuit incorporated into a chip or semiconductor; a whole system rather than a single component
