Electronic components fall under two categories;
Active Electronic components
These components have directionality and achieve some gain. Their electronic functionality is also defined.
Some of the components falling under this category include;
- Integrated circuits
- Logic gates
Passive Electronic components
These ones do not have a defined directionality and form a majority of electronic components.
They do not achieve gain and usually perform their functions in combination with other components.
Some of the components falling under this category are;
Now that we have learned about the two categorizations, let us jump straight into this guide of electronic components and their functions.
Electronic Components and Their Functions
Thank you for reading up to this point. We are the best Kenya Electronic Components suppliers.
I will now introduce you to our components shop. With us you will get IC’s, Transistors, Diodes, Filters, Resistors, Capacitors, and much more.
Kindly read through our electronic components and their functions guide to see what we have in stock for you.
IC’s (integrated circuits)
Integrated circuits (ICS) can be categorized into 5 classes, namely;
- Small-scale integration (SSI) These contain 3-30 gates per chip
- Medium-scale integration (MSI) They contain 30-300 gates per chip
- Large-scale integration (LSI) These contain 300-3000 gates per chip
- Very large scale integration (VL SI) They contain more than 3000 gates per chip
- Ultra large-scale integration (UL SI) These contains millions of gates per chip
Further to this, we can sub classify IC’s into 6 types.
- Hybrid or multichip IC’s
- Thin and thick film IC’s
- Monolithic IC’s
- Digital Integrated Circuits
- Analog integrated circuits
- Mixed-signal integrated circuits
Types of Integrated circuits
Hybrid or multichip IC’s (operational amplifiers)
These types of ICs are the most used in the amplification sphere. This is so because of their multi specifications and hybrid nature.
They contain both active and passive components and are mainly used for high-power audio amplification in the range of 5 watts and beyond.
Thin and thick film IC’s
In these ICs, active and passive components are detached and only combined to form the chip as one block.
Formed on a silicon chip, these are the most used ICs. They contain both active and passive components and have a wide variety of uses.
They are used in; amplifiers, voltage regulators, AM/FM receivers, and also in computer circuits.
Digital Integrated Circuits (Logic Circuits)
Microcontrollers and microprocessors fall under this category. They incorporate millions of logic gates and work on the Low and High or ON and OFF mode respectively.
Analog Integrated Circuits
Used for amplification, filtering, modulation, demodulation among other functionalities, These ICs work by processing continuous analog signals.
Timers and sensors fall under this type of ICs
Mixed signal Integrated Circuits
These types of ICs incorporate both digital and analog signals.
Types of Transistors
Without transistors, I doubt there would be electronics. This is so because, they are vital components and the building blocks of electronics.
Built of a semiconductor material such as silicon or germanium, a transistor is an electronic component that is mainly used to amplify signals and also acts as a switch.
A transistor has 3 terminals; Emitter, Collector, and Base. These terminals are connected with other components within a circuit to attain some intended results.
We could indeed say that transistors are gates that open and close when triggered by some action. It could be a signal, voltage or current.
Well, there are two main types of transistors. They are; Bipolar Junction Transistors (BJT) and Field Effect Transistors (FET).
Under the Bipolar Junction Transistors, we have the NPN and PNP Transistors as shown in the symbols below.
Under the Field Effect Transistors, we have the Junction FET (JFET) and Metal-oxide Semiconductor FET (MOSFET) as indicated on the image below.
Additionally, see the transistor tree below (Transistor images credit | worldwide web)
A capacitor is a passive electronic component that is used to store electrical energy into an electrical field. This effect is known as capacitance. (Capacitance=electric charge/Voltage. C=Q/V
Types of Capacitors
There are several types of capacitors and all of them have various capabilities and applications in the electronics sphere.
In addition, they come in different shapes and sizes and they are made of different materials depending on their functionalities.
Capacitors can be classified into four main categories which are;
Fixed Capacitors; They have a fixed capacitance. Their capacitance and functions are aligned with the dielectric used to make them.
Variable Capacitors; Their capacitance can be varied. Mainly used in the frequency tuning of radios.
Polarized Capacitors; These have both the positive and negative polarity and can only be connected in one way in a circuit.
Non-Polarized Capacitors; They do not have a polarity and can be randomly inserted in a circuit.
The main types of capacitors are;
- Electrolytic Capacitor
- Mica Capacitor
- Paper Capacitor
- Film Capacitor
- Non-Polarized Capacitor
- Ceramic Capacitor
A diode is an electronic component that is made of semiconductor material and allows the flow of current in one direction.
It has two leads namely, the Cathode (+) and the Anode (-) and is also used for rectification.
Types of diodes
There are over 25 types of diodes. These diodes perform various applications within electronic circuits mainly in regards to the transfer of current.
I will list the most common ones and give brief descriptions of them below.
- Zener diodes
- Schottky Diodes
- Laser Diodes
- Tunnel Diodes
- Backward Diodes
- Vacuum Diodes
- Shockley Diodes
- Thermal Diodes
- Rectifier Diodes
At House of Electronics, we stock a wide variety of resistors. Kindly talk to us if you need any type of resistor on phone number 0721 949815.
Voltage regulators play a very critical role in the electronics world. This so because they help us achieve certain set voltages.
With these regulators, certain critical and sensitive components like microprocessor IC’s are protected from damage due to over voltage.
Regulators work in a similar manner to a switching transistor. They have three pins. An input, output, and ground.
The output produces the set voltages notwithstanding the input voltage. This way the voltage critical components perform optimally.
We stock DC voltage regulators.
