Electronic Components Online

Buying electronic components online is an easy way to get the components you need. There are many stores that sell electronic components and many can ship worldwide in just a few days.

If you are a beginner, it might be useful for you to read about the basic electronic components found in circuits.

Where can you buy electronic components online?

There are many online stores for buying electronic components. I like to order most electronic components online from Digi-Key. They have a large selection of components and really fast shipping. I live in Norway and it usually only takes two days to get my order from them.

Hard-to-find components

Sometimes you need a special component that you cannot find in the general purpose online stores. Like an integrated circuit that is hard to find. Or some special connector. Or a rare display.

When I am in such a situation, I have a few strategies. If it is a chip that I am looking for, I use findchips.com. To find other special electronic components online I first do a quick search on all the component stores that I know of. If I can’t find anything, I use Google to try and find a manufacturer of the part. Then I visit the website of the manufacturer to find their distributors.

What to consider before buying?

Before you buy your components online, you should consider a couple of things.

Choosing components

When choosing which components to buy, there is always a chance of getting confused with all the choices. Learn how to choose the right capacitor type, find the right type of resistor, and choose between LED types.

Also check out what an inductor is and learn how a relay works and how a transistor works.

Component packages

What packages do you need for your components? Is it surface mount devices or through-hole?

Getting the right package for your components makes your soldering much easier. If you get the wrong package you might not be able to use the component at all.

If you haven’t designed your circuit board yet, you can buy whatever package you like and just make sure you design your board with that package. You can also design a custom component in your design software to match the component you find.

Brainstorm all the things you need

I cannot count how many times I have sat down to solder an electronic circuit just to realize that I’m missing something trivial as jumper wires or solder paste. Therefore, brainstorm what else you need.

Do you have the soldering tools you need? Solder and solder wick? Do you have the necessary wires and cables? Do you need an enclosure? Do you need an external power supply? Batteries? Do you have the necessary debugging tools for troubleshooting your circuit after soldering?

Write down all the accessories you need so that you have a complete list of things to order.


Are you ready to order your components?

  • Have you found an online store to buy your components?
  • Have you made sure you found the correct package for your components?
  • Have you listed ALL the things you need besides your components?

If so, push that “Buy” button and let the components come to you.

  1. Hello,
    I m a beginner and started my interest in electronics 6 months ago. A neighbor’s flat screen died and they threw it out. I managed to fix it by watching YouTube videos but really had no idea what I was doing.
    Anyway you have been very helpful with this new interest. It is becoming a passion. I wish I had not waited till I was 40. I always assumed I would not be able to do this.
    To sum up: I wanted to say I feel guilt that I have not been able to order your book(which I really want) but I lost my job a while back and simply living day yo day. Your sites have been so helpful that I feel I owe you something. As soon as things improve I will order it.Thanks for your help,

    P.S. Your English is excellent

  2. I’m Tai from Vietnam. It’s quite difficult for me to find out the electronic information by Vietnamese.Thanks a lot. This is very useful for me, I am really excited about knowledge above. Hope to see other ones in the future.

  3. Hi
    i am glad that i chanced upon your videos on youtube and finally landed on this amazing website.i simply love spending time on your page and videos and looking forward to buying your book materials.
    but one thing that is disturbing is the frequent flashing of the message about the FREE CHECKLIST. it appears almost on every single page and after a time it becomes quite irritating.just when i am about to go deep into reading all the stuff this message flashes and it is quite non-responsive,i.e.,it doesnt disappear even when i click any of the options.so i am forced to reload the page often..very often..please look into this issue..
    apart from that..you are doing a great great job in explaining mammoth concepts just like rhymes ;) Thank you :D

    • Hey, thanks for the feedback! It’s only suppose to popup once on your first visit, and I’ve designed it with buttons to hide it right away. But I guess this is not working for you. I’ll look into it and see if I can figure it out. Thanks!
