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

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