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!

As an Electronics Engineer, this a very good approach and explanation condensed in 12 minutes! Many thanks and keep doing these videos

[@rklauco]

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.

[@stanrock01]

Me as well. I just wish there were less formulas and more rules of thumb like this video!

@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.

This is so helpful. I wish I could show this to every guitarist ever. Quantifies why different caps sound different.

[@jmannUSMC]

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.

[@heltonritter]

You did a great job balancing sponsorship and content itself. Thanks.

[@waliulhamim2542]

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!

[@ucantSQ]

Phenomenal content. I love how much detail is given to a seemingly simple subject. Great job, as usual.

[@felipe_lopez]

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.

[@russelbanze]

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.

That was a great explanation. Well done, and thank you very much.

[@Molafa]

Amazing very informative video, as always! Thanks a million!

[@KiR_3d]

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!

[@michaelhoste_]

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.

[@winstonsmith478]

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."

[@isettech]

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.

[@southerncharity7928]

[@BigDaddy_MRI]

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!!

[@PrashantSingh-br6dk]

Thanks man It was a very good explanation

[@Taran72]

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.

[@sincerelyyours7538]

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!

[@jasoneyes01]

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.

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.
