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!
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.
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.
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.
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
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.
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.
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.
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.

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?
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).
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...
Similar thing happened with Sanyo. They've spun off their capacitor business into a separate company 10+ years ago. The name and logo changed (now Suncon), the caps stayed the same (ie they kept the same series with the same specs in production). Nice side effect: the chinese fakers still don't seem to have gotten the memo yet, so they still happily print SANYO on their fake WG series (or whatever) caps. At least this makes it super easy to spot fakes (if the abysmal print quality, wrong top vent and circular rubber bung aren't enough of a giveaway)
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: ruclips.net/video/_6-_jvZe7iA/видео.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 ❤.
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!)
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.
Another advantage of the polymer capacitor is there is no electrolyte which may seep from the capacitor, causing leakage paths on the PCBA and corroding the copper traces, eventually leading to open circuits.
Best coverage of this component I've seen in my 30 years of electronics. Question: the conductive polymer and the hybrid capacitors have no vent.... what happens in reverse polarity? Are they less dangerous than the standard liquid electrolytic capacitors?
Quite the opposite. Solid polymer caps turn into literal bullets when they fail, shooting the metal can off of the base. Thankfully this doesn't happen much because _a lot_ needs to go _very_ wrong for them to pop. But if they do, you better hope you're not anywhere near it
Interesting. I believe that I have seen some electronics guys discharge capacitors using screwdrivers and jumper wires. Some used resistors, but I am not sure that all did.
I never short out capacitors, I think it's terrible practice. Apart from anything else, you don't want sparks flying around on boards with sensitive components.
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. 👍
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.

This was actually fun to watch. Seeing how those capacitors performed in the dry ice was especially cool! 😉
Very clear explanations! I'm loving your videos Ichiken sensei
Nippon chemicon it's one of The Best caps Ever, tks for The great vídeo, 🎩
A very good breakdown of modern capacitors. It explains why caps are smaller these days. Thanks for sharing!
In one glance i understood the function and characteristic of capacitor. It will be very helpful in my day to day job role.
This guy do a good job by showing diffrence in using other type of capacitor

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.
Wow, this is really informative. It's given me some great ideas for improving my power supplies.
Brilliant video and introduction to different types , also never thought of esr in parallel. You live and learn .
Excellent video! Very informative, and at times humorous. Well done!
The best explantion of electrolytics that I have seen. Keep up the good work.

I wouldn't even think of using Chinese electrolytics without at least testing them first & i certainly wouldn't use them in a customer repair.

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.

"The electrolyte IS the cathode". You are illuminating things for me. Thank You. I'm very excited to discover your channel.
