What are electronic components?
Electronic components are devices that are part of an electronic circuit. As there is a great variety, they are usually installed in different types of materials such as ceramic, metal or plastic.
Types of electronic components
Resistance
It is an element whose main feature is that of resistance to the passage of current. Its unit of measurement is Ω (Ω).
Some of its applications are:
- Divides the voltage
- Protection of voltage sensitive devices.
- Current limitation in a circuit
Capacitor
A capacitor is a device that stores energy in the form of an electric field. Its average unit is farad, since farad is a very large unit of measurement, μf (microfarad) are usually used.
Some of its applications are:
- Filter to eliminate voltage ripples.
- Couplings between amplifier stages
- Low pass filters
- Radio receiver or oscillator circuits.
Coil
The coil stores energy in the form of a magnetic field. Each cable through which a current flows has a magnetic field created by the current around it.
Some of its applications:
- Electric motor
- Door bell
- Transformers
- Transponders
LED diode
It is a special type of diode, which works like a common diode, but when electricity passes through it and emits light. There is a wide variety of colors. Its applications are mainly based on visual indicators.
Passage
Its operation depends on the polarization applied. In reverse polarization the diode acts as a switch. In direct polarization it lets the current pass but creates a voltage drop of 0,7v.
Some of its applications are:
- Protection of electronic circuits or devices.
- Trimmer
- Rectifiers
- Voltage multipliers
- Switches
Transistor
It is an electronic component formed from semiconductor materials, very commonly used. We find it in any everyday device such as radios, alarms, cars, computers, etc.
A transistor is a component that has two basic functions:
- Passes or cuts electrical signals from a command signal (switch).
- Acts as a signal amplifier element.
Transponder
It is a switch that works magnetically. Turns on or off when the electromagnet is on. This function causes a connection or not between two or more device terminals
Applications
- Remote device control
- Activation of low voltage to high voltage
- Isolation switch
Potentiometer
Its operation looks like a resistor, however the value of the resistor is variable and can be changed manually.
Applications
- Circuit voltage regulator.
- Variable voltage dividers in a circuit.
Electrical safety
Used to protect an electrical circuit from excessive current. Its main component is usually a metal wire or tape that melts at a certain temperature. Its most notable application is overvoltage protection.
Transformer
This component is responsible for reducing or amplifying AC power, generally applicable to power supplies.
