List of Basic Electronic Components

List of Basic Electronic Components | Basic Electronic Components | Scoop.it

Here’s a list of some of the basic electronic components you will encounter in most devices according to Utsource eBay

Samuel Foluso Olabode's insight:

The smallest part of the building blocks of any electronic equipment is electronic component. They vary in  sizes and perform different functions in diffrent circuits. Correct connections of interrelated components enable the device to perfom desired functions be it in computer, automotive, bio-medical devices, industrial control, and lots more, just name it.


Your status notwithstanding, for you to work confortably and successfully on any of those equipments, you need to have good knowledge and understanding of components. The components include tansformer, diodes, resistors, capacitors, transistors, voltage regulators, relays, and many more.


You need to be able to identify and distinguish each component from the other, characteristics, limitations, Lead information and lots more.

Microbatteries: The most powerful batteries are only a few millimeters in size

Microbatteries: The most powerful batteries are only a few millimeters in size | Basic Electronic Components | Scoop.it

Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery – and then recharge the phone in the blink of an eye. Developed by researchers at the University of Illinois at Urbana-Champaign, the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics. Led by William P. King, the Bliss Professor of mechanical science and engineering, the researchers published their results in the April 16 issue of Nature Communications.

 

“This is a whole new way to think about batteries,” King said. “A battery can deliver far more power than anybody ever thought. In recent decades, electronics have gotten small. The thinking parts of computers have gotten small. And the battery has lagged far behind. This is a microtechnology that could change all of that. Now the power source is as high-performance as the rest of it.”

With currently available power sources, users have had to choose between power and energy. For applications that need a lot of power, like broadcasting a radio signal over a long distance, capacitors can release energy very quickly but can only store a small amount. For applications that need a lot of energy, like playing a radio for a long time, fuel cells and batteries can hold a lot of energy but release it or recharge slowly.

 

“There’s a sacrifice,” said James Pikul, a graduate student and first author of the paper. “If you want high energy you can’t get high power; if you want high power it’s very difficult to get high energy. But for very interesting applications, especially modern applications, you really need both. That’s what our batteries are starting to do. We’re really pushing into an area in the energy storage design space that is not currently available with technologies today.”

The new microbatteries offer both power and energy, and by tweaking the structure a bit, the researchers can tune them over a wide range on the power-versus-energy scale.

5v fixed Voltage Regulator

5v fixed Voltage Regulator | Basic Electronic Components | Scoop.it
A regulated power supply is very much essential for several electronic devices due to the semiconductor material employed in them have a fixed rate of current as well as voltage.
Samuel Foluso Olabode's insight:

The 7805 voltage regulator produce at its output a fixed +5V but in order for the IC to work effectively, the input voltage must be greater than 5 V. Remember, it is essential and very important to power a digital circuit with this kind of IC. If you are looking for a regulated -5V at the output you need to use its negative counterpart IC 7905.

 

You can see from the above picture the volltage regulator pinout. the input where you connect the input voltage with respect to ground GND, and the Output where you tap the +5V. Be careful to connect the IC correctly to avoid damages.
