Electrolytic Capacitors: Comprehensive Overview, Teardown, and Experiments 

Thanks Chemi-Con for supporting Denki Otaku, making Japan great again one capacitor at a time!

Very nice collaboration and informative video! It was great to have the EC differences spelled out.

Hello from Canada. I like how you present your content and the English translation makes me keep coming back as I continue to learn. Keep up the clean, clear, and greatly informative videos. You’re doing great!

Excellent video! Very well put together information, thank you.

The best explantion of electrolytics that I have seen. Keep up the good work.

What an amazingly educational video. I have been in in the electronics business for 60 years, and this is one of the most clear and useful explanations I have seen on electrolytic capacitor technology and characteristics.

Very clear explanations! I'm loving your videos Ichiken sensei

I'm so impressed with this video. You managed to explain simple way what is the difference between electrolytic and solid caps. Domo arigato BTW Chemi-con was always my favorite brand of caps

Fascinating and informative. I didn't expect much at first, but as I got deeper into the video, the subject began to open up for me.

Excellent explanations ! I was amazed at the results of freezing the electrolytic capacitor and demonstrating its discharge curve. It made total sense to me when you did this. It was something I have never though of before. Makes you wonder if any "antifreeze" types of electrolytes have been researched. Probably so.

That's why they always add an extra capacitor, That you think is not necessary but it is because it's preventing the other one from falling apart, Thank you for this well explained explanation. I was always curious about this.

Clear and simple explanations. Thank you for your video!

Very informative video with information I had not previously considered. Thenk you.

This video answered a lot of questions for me. Thank you.

Very good information and demos. Thank you.

Thanks. Great presentation. Learned alot.

Well done. Well done, Sir! Very educative. Thank you.

FANTASTIC explanation!!! Thank you for this video! It is highly appreciated!

Very good documented and explained video. Thank you!

Super lessons about capacitors in electronic device . Thank you so much.

Excellent video. Thank-you from Canada

Very informative and fun video. Arigato!

Really cool video, thanks!

Excellent information. Thankyou.

excellent ! thanks for this clear presentation.

Great presentation. I've unsoldered many types of these caps from PC bords but didn't know the differences between them. Now I have an idea. SUBSCRIBED.

Thank you for a very informative presentation.

Thanks for sharing, awesome video

Brilliant video and introduction to different types , also never thought of esr in parallel. You live and learn .

This was very nice demonstration. Thanks a lot.

Excellent presentation!

Very good and informative, thanks a lot.

Superb! Great Graphics, too.

Thank you for this very informative video. Can you please specify the composition of the electrolyte? Also what are the cathodic and anodic electrolytic reactions during charging?

Excellent video. Thanks!

Thanks. Very good!

Very good video,thank you for the English translation.

Great video which is very nicely brief

Excellent video.! Look at that Teledyne oscilloscope -- wow!

Excellent 👌 keep positive such videos

Thank you so much for your useful video. I am a retired Radio Officer for 23 years and I want to learn more in details about electronics!

Very informative, presented so even a novice can understand it. Thanks so much.

Very good and informative video indeed.

THANK TO YOU AND LEARNED MORE HOW THE CAPACITOR ARE MAKE AND THE USES IN ELECTRONIC, THANKS. AND IN OTHER COMPONENTS.

Best video on capacitors on youtube. Fantastic demonstration, your oscilloscope makes me jealous.

A most Informative video.

Cool channel thanks for sharing the knowledge.

Nippon chemicon it's one of The Best caps Ever, tks for The great vídeo, 🎩

Excellent ..Thank you Denki Otaku

I had about 7 hours of research in capacitors in a general category and this video has taught me some useful information i didn't know of yet, Thank you for the video it's a much more entertaining way to learn instead of reading so i as well as some others with this same opinion have learned some of this information that otherwise likely wouldn't have been learned when avoiding forums, documents, catalogues, etc.

Excellent. Thx!

Nice informative video. 👍🏻

Great job!

Thanks so your information about capacitors ❤

Awesome video....stellar!

Thank for good explanation

Very informative video 👍

I have been trusting Japanese quality brands of electrolytics for a long time. Japanese electronics made as far back as the 70's still have good capacitors in them and they don't seem to need replacement, even though some people habitually do so out of worry. The capacitors that I do fear are ones made in China, or Chinese made fake copies of Japanese capacitors.

I'm surprised that Chemi-Con changed their name and logo. As an old timer, they will always be Nippon Chemi-Con to me, but younger engineers may not realize that these are highest quality Japanese capacitors rather than lower quality knock-offs...

Thanks! That's the basics

Well done, Denki!

Your really good teacher an your make it Interesting to watch an funny.... Great video 👍👍👍

Tam olarak anlamasamda,Harika bilgiler verildiğine eminim👍👍🇹🇷

Very good Explanation sir, thankyou very much sir,

Excellent content❤🎉🎉

Very nice video 👏

Thank you very much for the very instructive video. I should learn more about the technology inside electrolytic capacitors. What caught my attention were the pliers at 4:29. When I worked in Japan at a company with enough budget a local college bought very cheap pliers and he said it was just a cheap occasion. They got rusty after just a short time and I asked him to let me try to polish them and give them a little oil. He said he could throw they away any time, they were just cheap. We agreed to make the experiment and they looked better afterwards and were kept. Just a personal memory inside the very valuable lesson about maybe the best capacitors and their different types.

Thank you!

I understand it now thanks 👍😊

☺Thank you !

The polymer electrolyte capacitors do contain electrolyte (it's right there in the name), it's just a solid electrolyte instead of a liquid one. Technically, they're all "aluminum" capacitors as well (the electrodes are aluminum, and the dielectric is a layer of aluminum oxide).

THANK YOU.

Thank you very much

In one glance i understood the function and characteristic of capacitor. It will be very helpful in my day to day job role.

Awesome!

Nice information

very informative

nice info

Thanks

Thanks cool video

Nice... Good job. 😮😮!

cool! this was informative. thank you for translating to english. i have subscribed :)

Excellent

The best explantion of electrolytics that I have seen

This is a very good video nice to have a decent translater.

Very awesome man I appreciate your video so much especially with to no avail trying to figure out what happens when capacitors are super cooled .. so the ones without the electrolyte.. don't really seem to give off much of an advantage if anything noticable.. however I wonder if they charge quickly

Very easy to follow, explanatory video, thankyou. I was hoping you were going to reverse polarity on one of the hand grenade sized caps 🤣. Keep up the great work. 👍

This is a very informative video and educational at the same time. May I ask, would it be better just to use the solid type capacitors in vital cicuitry like processors to avoid damage due to leaking caps?

Hello Mr Ichiken, this time, in the English version, you will present the construction intricacies of electrolytic capacitors. I believe that the condition of increased capacitor operating voltage by approx. 25% should always be met. Congratulations! Recently, I have performed tests that can be referred to in three groups: First: Use of the base Controller and 230 VAC/62 V/17 kHz//0.65 kW Power Supply to run the BLHF-RM (compound coil micromotor, phase angle 180 degrees). The total power of the control lines [L1 - L3] and [L2 - L4] = 128 W during the average rotation of 28.705 Hz = 1.772 kRPM was obtained; load current max = 7.32 A; PF approx. = 1. Overheating of the IGBT key transistors (too much forced in previous tests) was found, which caused irregular voltage waveforms, but regular current, close to rectangular. The author's earlier tests led to the same conclusions contained in the film by the renowned Texas Instruments company, address: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_6-_jvZe7iA.html. Second: BLHF-RM (compound coil micromotor) powered by BLHF-RM No. 3 (phase angle 135 degrees; P = 6.17 kW - as a generator, driven by an angle grinder 230 VAC/5.5 kRPM//2.1 kW). The total power of two control lines = 0.203 kW; PF of phase windings = 0.7108. The value of the reduced power factor was affected by the different angles of the location of the magnetic poles in the armatures. Third: Powering the micromotor with the frequency converter XSY - AT 1/1.5 kW. Data: f = 344.00 Hz = 20.640 kRPM; RMS = 23.36V; I (loads) = 11.20 A; cos φ = 0.9008; P = 0.236 kW (power record!). Load current interpreted by the ideal sine function (!). It should be noted that the author conducts tests on the basis of devices constructed at home and on a low budget. I invite you to visit my You Tube channel and website: www.mojewynalazki.pev.pl. My new study, Chap. VD. I cordially invite and greet all Internet users ❤.

Very well explained video, Love your way of teaching, a very Interesting subject. Would be possible to do a similar tutorial about tantalum capacitors and why they are preferred in the RF field especially in old RF equipment(wet tantalum caps)? Anyway thanks for sharing your knowledge.

I love this ❤❤❤❤❤

That was a very interesting video, nice to know the brand has a new name, before I beginning to complain about why I can’t find them.

Thanks bro

A very good video.

Never seen you before but your very funny. Thanks for the video.

Nice temperature demonstration

Excellent introduction. Capacitors are often the first failure point in power systems and unfortunately they are also the component many cost conscious engineers try to save money on. This video gives very concise guidance on why you should never cut corners on capacitance. When you think about it your entire design runs upon the assumption of clean available electrons to do the work intended. Why would you jeopardize the integrity of that need? (I also liked the fact your hair grew during the video!)

A very good breakdown of modern capacitors. It explains why caps are smaller these days. Thanks for sharing!

Спасибо, очень полезное и интересное видео!

Thank you very much . Your explains over the Technology of modern CAPACITY are good . Rainer Peetz from Kiel / Germany .
