Super Capacitor vs Regular Capacitor and WHY I will NOT use Super Cap
Вставка
- Опубліковано 5 лют 2025
- Supercap is a great product for packing more capacitance into a small package compare to regular capacitor. However, the dark side of supercap which very few are saying. Someone has to tell the story from another side.

As usual; learning here in a manner I don’t get anywhere else. Thanks!
Thank you for the education.
I’ve become more and more aware of the importance of a quality power supply in audio .
Great class AGY. Always learn something new, as well as hear the eight approach to building/repair. Quality and assurance.
Did I actually have said eight approach in the video? Or you are just figure of speech...ing.
@@angela-gilbert hahaha. I mostly use voice to text and never proof read. I believe it should be right instead of eight!
@@MrMersh-ts7jl Ah, ok. You know I have tried speaking ching ga lish into one of those voice to text. It got really messed up. 😜🤩😃
@@angela-gilbert haha. Mines still US, but heavy on the state of Maine accent. Screws it all up
There are no videos that compare to these! I learn so much .. thank you A-G for taking the time to educate us. ❤
Great discussion and valuable insights.
Supercaps in a DAC power supply does wonders to improve the sound quality. At 3.3v, digital circuits are great candidates. Two caps in series work well with tons of safety margin.
At 3.3V, two of the 3volt supercap offer plenty of safety margin. Unfortunately, not the same case when we are dealing with 30V or more.
@@angela-gilbert Agreed. I won't even try for 16v supplies. But at 3.3v a pair of caps don't even need a balancing circuit. I also find that a small 1.5F cap does a lot. Many agree that 300F is better, but now you're into big money, massive and dangerous.
Omg I lost my lunch when you moved the camera 😂😂. Going through a treatment for my tumor and I get queasy easy 😂. Great video . I learn so much from your videos but will never be like you . U r phenomenal 🎉❤ big fan of your artistry
@@marklloyd4153 🥳😜🤩 Did you close your eyes when I move my camera? Next time I Will let people know to take out their sea sickness pills and bracelets. 😛😝🤔
@@angela-gilbert 😂😂😂😂 it’s worth it . Your videos are so good so fun and beautiful . Your work is art
There is also another reason, why many small capacitors in parallel are better than just a few very large capacitors: when connecting, the capacity adds up but the impedance every capacitor has, gets smaller. High impedance slows the charging and discharging process down. There are some manufacturer who prefer many small capacitors rather than one or two large ones. Anyway, nice video. Thanks.
Agreed.
Another great video with real facts and education.
A lot of time real facts are not popular. Topic such as this is not popular on UA-cam because I am pointing out the weakness of supercaps.
Thank you . Very educational.
Thank you! I learn something new from each of your videos. Now I have a question. I sent up my Yamaha AS801 up for a modification. What goes into that update? I trust you so much that I dropped off my amp without truly knowing what’s going inside of the unit😄.
Thanks, Bill S from Detroit
I got my 701 back from AGY about 4 months ago . Sounds great!
@@yuknasty1013 thank you.
@@ibdam1The more you play it the better it gets.
We install a bunch of capacitor inside the AS801. Result is about 4.5 times more than the original capacitance. That's the basic of it. The how we do it is also the key to the improvement.
@@angela-gilbert thank you.
Always a treat thank you.....Pinky😍

Solid state vs valve a hot topic 🙂
@@garthdev It is a topic with no right or wrong answer. Apple or peach, both are fruit. Taste very different. Both can be used to make pie.
Other then the extra current usage, what is the issue using Balancing Resistors across the capacitors?
Or, using Auto Balancing (SAB) MOSFETs?
@@neccron9956 Becausr it simply doesn't work. You van bring pre-made supercapacitot package made by the manufacturers and the voltage drop are all over the places. By the time the amount of current has to be drawn in order to balance the voltage, it defeat the purpose of using super cap.
Are you going to be at audiofest this year?
@@MasterofPlay7 No, we are not. However, Entracte Audio is going to have an invitation only open house on November 3, 2024. All three of my recent prototype preamps including Pinkie are going to there for active demo. We have figured it is better to do demo at a dealer than at a show.
That makes sense to me
@@Coneman3 Are you coming?
I wish. I’m in the UK, a long way away
@@Coneman3 That's too bad.
What do you do to protect the power supply adding the super supply from creating too much
turn on current? How would you do a supercap supply for diode bridge to my two single caps running on 80 +- Volt Rail?
@@charlesnr Multi stage soft start to control the industry current.
Are you saying using supercap to run a +/- 80volt power supply? It is possible but very costly.
Just a little tidbit to make it even more complicated: There are about six different kinds of "regular capacitors," all with their own particular strengths and weaknesses. Not just ceramic and electrolytic anymore.
@@jamesmurphy449 Are there only six? Each topic has so many sub-topic there are endless opportunities for discussion. Nobody on earth knows everything.
@@angela-gilbert Well, I recently went to buy some "electrolytic capacitors," and discovered that that term is basically obsolete, as is the concept of 'lytic cap we all remember from the 80s and 90s. So I shared what I found.
I'm an EE and my main experience is in electronics manufacturing. And you're absolutely right, nobody knows everything.. but we definitely do know what products are made and available when it comes to capacitors!
I see SC's used most in applications where peak current and voltage stability over time are not crucial; just long-term power storage. Kind of like a battery. Tried to replace a battery with a SC once, but it wasn't as good and I just got another battery.
@@jamesmurphy449 SC is nowhere near as good as battery as a long term energy storage. They are mainly for medium term low discharge application. Use them replace the battery holding a memory inside a PC or laptop is not a bad idea. Use them as backup storage for low to medium low current draw with regular electrolytic capacitor is ok too but not all by themself. The so-called hybrid lithium-ion supercap is another story. They are really a lithium-ion battery in a capacitor package.
Overall, I have no argument with your point of view though.
👍👍
Gryphon uses 79.000uf 300v
CH precession uses 47.000uf 400v
Piooner m22 uses 39000uf 300v
Ok now i see. I believe you . take e battery and make it into a capacitor bank. so maybe it can balance dc voltages?
❤
Cool
What caps wear out after only 14 months? If that’s the case you are using some crap capacitors. They should last 150,000 hours or more, which is around 18 years!
Did I say wear out? I said some manufacturer's warranty period for their supercap is only for 10,000 hours. Which is not the same as wear out. Most of them don't publish their warranty period. Read their fine print. Look at their estimate capacitance variation graphs. Have you thought about why they are an estimation? What were they based on?
@@angela-gilbert If you are concerned with a capacitor’s warranty period, then you chose the wrong capacitor brand. With a good capacitor you wouldn’t ever need a warranty. And with high end audio gear, having your caps replaced after say 10-15 years is not an issue if its a high quality device, but most people won’t even need to worry about that. If you are spending say $5,000 on a DAC or Pre-Amp then cap maintenance after a decade is not a big deal. You are talking $150-200 to replace all,the caps on a $5,000 high end piece of gear.
@@BrentLeVasseur It it very obvious you don't understand what is the video topic is. Have a good day and good bye.
@@BrentLeVasseur capacitor brand? its not even 1990 its 2024. there is no such thing.....or no way to tell.
you could get a toyota corolla for your wife or kids for $5k. it probably has a radio and speakers
Stay safe bye 👋

✨👋 see you soon during the Audio Fest. '24.
But I am not going, sorry.
The wig is a bit much...but enjoyed the video.
😆😆😆😛😛😛🤩🤩🤩 If you are thinking wig as literally wig, that's real hair. If you think my hair style if a bit much. That's ok too.
@@angela-gilbert 😂😂😂😂😂
Cheap garbage junk pos 10000uf 65 is trash
Use 33.000uf 500v
I don't think you know how capasitors work.
