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!

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

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

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.

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

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

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.

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.

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.

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...

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.

Thanks. Great presentation. Learned alot.

Clear and simple explanations. Thank you for your video!

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?

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

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

Very good information and demos. Thank you.

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

Thanks for sharing, awesome video

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

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

Thank you for a very informative presentation.

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 good and informative, thanks a lot.

Thanks so your information about capacitors ❤

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

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

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.

Very good documented and explained video. Thank you!

Very informative and fun video. Arigato!

Excellent information. Thankyou.

Excellent. Thx!

excellent ! thanks for this clear presentation.

Superb! Great Graphics, too.

Excellent presentation!

Thanks! That's the basics

Really cool video, thanks!

This was very nice demonstration. Thanks a lot.

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 video. Thank-you from Canada

Cool channel thanks for sharing the knowledge.

Excellent video. Thanks!

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

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

THANK YOU.

Awesome video....stellar!

Thank you!

Thank for good explanation

I understand it now thanks 👍😊

Great job!

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

Great video which is very nicely brief

The best explantion of electrolytics that I have seen

Very informative video 👍

A most Informative 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.

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).

Very good and informative video indeed.

☺Thank you !

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

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

very informative

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.

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?

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

Thank you very much

The 2 silver color capacitor can it be used on audio amplifiers?

Nice... Good job. 😮😮!

I tried to identify a capacitor that I need to replace. Looks like a conductive polymeric hybrid Aluminum electrolytic capacitor. The number in the top are 98sk10050v, k9f2216v, and 9ek4716v. Any idea of what capacitors are and the supplier or replacement?

Very nice video 👏

I love this ❤❤❤❤❤

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.

Thanks cool video

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

Nice information

Thanks bro

Very good Explanation sir, thankyou very much sir,

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 good video nice to have a decent translater.

Thanks

nice info

Nice temperature demonstration

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: ukposts.info/have/v-deo/l2Zek6CtkZtoynU.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 ❤.

Thanks. How to oxidize anode?

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!)

Thanks for the very informative video. I found it distracting that "anode" and "Farad" were not pronounced correctly, however.

I liked the haircut changes through the video. Good info too.

This video was so helpful. Can you please tear down multilayer ceramic capacitors and Film capacitors. Like do a vid on them too like this one.

It looks like there's some HF noise in the lab. Judging by the spikes on the oscilloscope, I suspect either light switching spikes or more likely cellular phone interference nearby, around a few meters away. Also looks like the 'scope leads might be near a transformer or they're growing resistive in the shielding, as there is a LF ripple apparent. You covered etching of the foil nicely, many classes on electrolytic capacitors omit that critical fact. I'd probably have gone lightly into inductance in capacitors, especially electrolytic capacitors, just to be thorough on design considerations and a small ceramic or mylar cap to counter ringing. Haven't worked in electronic circuit design in decades, nearly forgot about frozen electrolyte. Good to remember if I ever design something for arctic, high altitude or space usage. Unlikely, but in my life, the unlikely occurs far too frequently. Back when I was working as an electronics technician, I worked on everything from vacuum tube analog, germanium transistor analog, silicon transistor analog, discrete IC analog, VLSI analog and digital circuits. I work in IT now, but still remember my electronic theory well, which has saved my bacon on more than a few occasions. Knowledge is power! And equally important, useful.

Thanks for the excellent video. Heres a thought, why not use an electrolyte on both sides of the center insulation, not just on the negatve (cathode) side? would that increase the capacitive storage ?

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