In this video we will have a closer look at a decoupling problem of one of my recent LED circuits. That means I will explain how a decoupling capacitor can save my circuit from harmful oscillations. Along the way I will talk about three popular capacitor types, the film capacitor, the ceramic capacitor and the electrolytic capacitor and explain which one is best suited for which application and why. Let's get started!
Thanks to the Würth Elektronik eiSos Gruppe for sponsoring this video.

As an Electronics Engineer, this a very good approach and explanation condensed in 12 minutes! Many thanks and keep doing these videos
This is a perfect video. I wish something like this was used in school while I was studying instead of the lots and lots of equations with no real world understanding. It took me years to find it out myself, this single video would shorten my learning curve to minutes instead of months or even years. THANKS to both you and Wurth Elektronik for providing you the design kit.
This is what I consider spot-on partnership.
Me as well. I just wish there were less formulas and more rules of thumb like this video!
i dont mean to be so off topic but does anybody know a tool to log back into an instagram account..?
I stupidly lost my account password. I love any help you can offer me
@Hugh Tyler i really appreciate your reply. I got to the site thru google and I'm trying it out atm.
Looks like it's gonna take a while so I will get back to you later when my account password hopefully is recovered.
@Hugh Tyler it worked and I now got access to my account again. I'm so happy:D
Thank you so much you saved my account!
@Major Beckett happy to help xD
Thank you for making English versions of your tutorials.
Same!
@michel777ification only one
This is a very helpful information dense video. It definitly earns a bookmark. Thanks for posting.
Thanks for the feedback :-)
gute nacht great scotty!
I stumbled on Wurth when shopping for smoothing caps. I really loved how much insight they gave into their products. As a non electrical engineer I really appreciate when companies do that and it's so awesome that they even sponsor channels like this.
Me: slaps ceramic capacitor on everything
Seller: that will be one kidney and 19 cent
It's not that expensive

@@blackturbine bruh how the hell are you using 1000 4.7uf film capacitors for rectification filtering
@@johnyang799 at that point something's wrong with the power supply
*more capacitor*
@@blackturbine moar!!!!
Great Scott! That's what I say every time I see his penmanship. His freehand looks better than most fonts, and his wiring diagrams are cleaner than something in Fritzing!
I've been watching your videos for 2 years now and it's very interesting how I understand more and more of your in depth analysis as I go through my electrical engineering degree in college. Thank you for making quality videos and going so much more in depth than other videos. Huge fan!
This is so helpful. I wish I could show this to every guitarist ever. Quantifies why different caps sound different.
Phenomenal content. I love how much detail is given to a seemingly simple subject. Great job, as usual.
You did a great job balancing sponsorship and content itself. Thanks.
That's very very excellent content in video, the science behind the electronic component.
Thumbs up for Mr. GreatScott!!.
More great vids like this please! Always a pleasure seeing electronics concepts broken down and explained well. Thanks! Stay awesome and I will see you next time!
I think it's fantastic the way you can use a sponsorship to explain something that actually is useful to know. Keep up with this kind of sponsors and with this tutorials.
I just learned more about capacitors in this video then in the last semester at uni (I study electronics). love the way you give examples where one can use the different types. would love to see other similar videos about different components
I just wanted to take a second and thank Scott for all the great videos over the years vary easy to follow and vary helpful
The quality of your videos is amazing, i only managed to understand like 30% of all the info on this video but some day i will do 100% :D Thanks and greetings from Mexiko!
Excellent treatment of an often overlooked subject Scott. Nice one!
So much information dude....
It seems like engineering a capacitor is not that easy.
I've been subscribed for a long time in this channel but once again Dr. Scott, you are the most gifted & amazing teacher in the whole world (at least currently).
You go so much deep into details & you videos are always slow paced, a visual feasting & they heat up the cold deep inside my heart & knowledge.
THANK YOU Sir.
I wish we had a way to show you our appreciation.
Thanks for the feedback :-)
You are best teacher in the world.
I always wait for your next video. Thanks man
I really like the way you explain man, thanks :)
I love your channel!! Keep it up! It gives me all i need to learn about electricity, circuits and components!
Well explained (as usual) !
Thank you so much. Great video! This answered several questions for me.
I think this video could have gone on for another 30 minutes. Choosing the correct capacitor for a project is important based on what the circuit needs.
Very nicely done. I also selected the German video at first, and suddenly thought something went wrong with my iPad. 😂😂😂. I really think your videos are the best!!
Random Q&A a while ago
Question: would you make videos in German?
GreatScott: ...Nein
resistance is futile :^)
Perhaps the sponsor requires it
Link to the video and time stamp?
It was one of his Q&A videos.
@@Felix-ve9hs Damn BORG!
This was really helpful for me, I am learning electronics.
I had the same issue with a cyberdeck, I was curious what kind of a capacitor I should use and low and behold you’ve solved my problem! Thank you! 🎉
Awesome tutorial and great resource links. This is a good balance of education an sponsorship. The sponsorship is somewhat behind the scenes but that is goodwill for Würth and I will think of them when component searching. I hope they continue to support the channel.
This is a great way to do sponsorships. We get to learn more about a general part and you get more revenue for your hard work. Win win in my book.
As always thanks for providing us with awesome videos. Just what I needed. Thanks
This type of video may not gather quite the audience of your build videos, but they are extremely helpful for students.
Ahhhh I found it in simple plain and understandable language!!
Yeepee!!
As usual very nice tutorial. I have over 40 years experience with electronics and still enjoy watching your videos. Thank you.
Wow
Realy a great video! This helps people that are non ee engineers a lot
I am with you! Well explained, Thanks :)
The 2nd E in EE stands for engineer btw
That was the Video I looked for some months ago 😁. So I searched the web and found something I didn't understand much. But with the help of your video I understand a lot more now. Thank you for that😉
Fair play for the video in German. It takes a lot of extra work, well done 😁
Awesome! Thank you for going into so much detail!
I always think why we use Different capacitor types in Induction motor(fan) and normally different. A great confusion gets sorted. Thank youh Great Scott
That was a great explanation. Well done, and thank you very much.
Amazing very informative video, as always! Thanks a million!
Thanks for the in-depth analysis. 🙏🏼
Thanks a lot for this great webinar . It was indeed interesting and educationnal with , a cherry on the cake , your clearly writing
Great tut. thanx! Now I'm more lively understand what is the parasitic resistance and understand _why_ not to use electrolytic caps for power filtering!
What kind(s) of cap(s) of what value? Always look at the datasheet. From the TC4420 datasheet (cap values for most ICs are usually more definitively stated):
"The VDD input should be bypassed to ground with
a local ceramic capacitor. The value of the capacitor should be chosen based on the capacitive load that is being driven. A minimum value of 1.0 µF is suggested."
Late reply, the cap should be able to provide the capacitor load provided by the MOSFET Source Gate Junction. Higher load values require higher bypass cap values. For example, driving an International Rectifier IRF3805 is driving into a typical gate capacitance of 7.96 nF. At 100KHZ, this is considerable gate current. A 10nF (0.01uF) bypass cap is going to be inadequate. I worked on an inverter where one driver drove a bank of 4 of these transistors, so the minimum value of 1uF is a good start.
@@isettech sooo... Basically, read the data sheet again.
Wow, this was a really good video. I learned like three things that I didn't before, and didn't quite know how to ask.
Like, before watching the video. A fan from Italy.
Very fine video! I actually understood most of the theory for once. And thanks for the link to order free samples from Würth Electronik. I knew this procedure existed with other companies but always had trouble in the past. My foreign address or lack of a company name are the usual stumbling blocks. Had I known this procedure I could have avoided some of the $400 on various caps I just spent buying low volumes from several suppliers. More videos like this would be much appreciated!
We use Würth tools at work and their quality is second to none, but I didn't know that Würth sell electronic components too. I'll be passing this info to my Boss tomorrow.
Thanks! :)
Great video Scott! i would like to see more of these kind of video's
Got here from Adafruits Blog. Learned a lot thank you!
Thankyou sir i think their must be some unexpected bug had came a while ago...but now m very thankful of you
Very well explained ! Thanks for sharing !
Thank you, very informative and simple
WOW , good video !
i think it need to be in the basic playlist.
Very precise drafting and handwriting.
Another great video
Awesome as ever, thanks! learned something new as per usual :D
Thank you for a most excellent and informative video.
Excellent presentation and great refresher for me.
"GREAT SCOTT" ole chap...Another great video !!
Simply brilliant as always! Cheers.
Great video! I appreciated the practical explanation of each type of capacitor. What is also interesting is the fact that the power supply was slower in providing the initial current than the capacitor.
Thanks for making the video.
18 hours ago???
Wow. I’ve been trying to get rid of fast spikes on my power rail and big electrolytics dont help beyond a certain point. I’ve been wondering about adding some small film caps and up comes your video! Brilliant.
Highly informative. Wish I understood more of it.
Love this video's! For me 40% is too difficult. However I still like it a lot. Lezen a lot from these video's. Thanks you. Stay creative!
Nicely done,even when you know this stuff. And the cap self resonant freq, yep had totally forgot about that, i think i've never considered it, but its totally useful to know.
Wow... there's so much to keep track of when building electronics! I've only recently started playing around, and to do something as simple as lighten a LED on a button press requires me to watch a tutorial xD and I still have no idea what I've done after successfully turning on the LED...
Don't worry about me though, I have a fire extinguisher ready ;)
That is an awesome capacitor kit! My first thought was high frequency oscillating best to use ceramic. Electrolitics start “ringing” at high frequency creating additional oscillations. A transformer and capacitor would be the most effective in my thinking.
Thank you sooooooooo much live the way you explain
Another great lesson ! Thanks o great one !
Great video, explained well.
I remember the first time I read a datasheet in school and saw timings in nanoseconds. I was hooked.
Very useful video. Thank you so much
Thanks man
It was a very good explanation
Thanks for the informative video !
This is the right video, thanks man
Wow, really helpful! Might be using one of those for decoupling my 220v mains. haha
The pen execution is excellent
Very good description and analyze.
Super interesting! Can you also discuss about the difference between MKT, MKP type film capacitors? Their price seem to vary quite a lot. What are the practical differences?
Damn dude, you are good. Always learning something new on your channel. Thanks!
Awesome as always!!! Thanks!
Great video, as always. Thanks!!!
Have you thought about creating a playlist featuring electronic projects that we can undertake at home to learn electronics, similar to school labs?
just asking myself which capacitors to use on an audio project this morning. thanks!
Thanks for this educational video.
Thanks for the excellent video!!
thanks for 2 versions
das ist toll
Congratulations on 1M subscribers
Fantastic video! Thank you!!
Good explanation , good video.
It's a wanderful materual feed, thx!
Great explanation. Thanks
Very helpful video. Thanks.
Awesome! I've always wondered how big is too big.
Wurth are a great company, we use them all the time.
I got for free these set of capacitors. But it is a gift from a engineer to another engineer. Each capacitor has advantages/draw back that are clearly represented in the datasheets. Engineering is often making compromises.
I've come across caps from Würth Elektronik before on Conrad but i don't remember why i didn't choose them.
Looks like WE has neat demo kits and more components than i thought.
Did anyone notice a 'puff' of smoke rise when the LED lit up at the beginning of the video?
It's magic i guess xD
Great explanation😍😍
