you can use them as a paper capacitor even after electrolytes goes off but with low capacitance

Holy crap, I thought it was DATA from Star Trek for a moment...LOLOL

I've been keeping old electronic devices from the early 90's and 2000's example snes console, ps2 slim and crt tvs will these devices have problems with aluminum electrolytic capacitors if stored for a long time?

This guy is brilliant and knowledgeable.

In glorious low-def.

Hee, hee, so those lines inscribed on the top are a "pressure vent"? I thought the pressure vent was the rubber part on the bottom, which is designed so when it blows, all that corrosive juice gets sprayed onto the PCB, and into the other components!

I have a question about using electrolytic capacitors in power supplies. Is there any way of knowing if you should use polarized or non polarized ? Or do you just try it and if it doesn't work change it ?

Hi Mr Dave Jones I would like to see you make a video on how to solder film capacitors like polypropylene as film can melt with heat I looking forward to solder thru hole polypropylene but scared about it's melting point

And Dave knows (see his Tektronix 2245B refurb video) that you have to install them in the right direction!. Electrolytics do explode - Dave just about jumped through the ceiling... Just given you a little bit of the business, Dave. Super helpful video, Dave. Thanks.

alternative title: Roasting Electrolytic Caps for 6 minutes

I've never had anyone shake a capacitor at me for 10 minutes straight😅 and yes I know I'm 12 years late on this video

Drop the emotion and drama please.

my general impression of this video is that capacitors are dangerous and can explode and that generally everything is evil

The best part about electrolytic and tantalum capacitors is blowing them up. Now if you want to turn them into firecrackers, you have to be careful, but it can be fun !!!! 😁😁😁

Any chance we could get reissue of episode 33? Your production quality has improved dramatically since this was published, great work Dave, you are such an inspiration!

Is there any reason to use an SMD 1uF Tantalum cap over a ceramic? The datasheet for the part I'm using calls out a Tantalum, but i believe it's just due to ceramic capacitors historically not being able to generate higher capacitances. These days you can get 100uF, even 500uF ceramic capacitors.

Hey hey hey I'm electrolytic capacitor stop talking shit about me

Amazing intro!

he's not aged in a decade what

Dave is Steve Irwin of electronics -- he is genuinely excited by all these little circuit-populating critters! Love the channel.

That was excellent.

Electrolytic capacitors mounted on electronic circuits of devices manufactured after 1990 can remain unused for as long as possible without this disuse causing failures and depolarization in the electrolytic capacitors?

i have electrolytic capacitors mounted on electronic devices from 1990, how long can these devices remain unused and without the electrolytic capacitors failing due to disuse?

This is excellent. Helping me navigate components.Thankyou mate. New subscriber.

No ceramic caps:(

first rate, david.

You tube is 11 years old

I don't know if it's just me, but you sure scared me to use ANY capacitor. lol.

Thank you ,i have learned so much from you and you are a really great teacher.

U make me feel dumb ure smart tho.

Seeing that I spent 60k for a eet associate's degree. I understand everything u said. Scraping computer part to melt down. After I get a trash can full. Love the video. Thanks

Sir if i made a non polar cap with a capacitance of 470uf each what is the total capacitance of the two tnx

Good informative video....I have a question..I have a power amp and the filter caps are 7500uf ...if I replaced with 10000uf ... what will happen...and which brand is good for filter caps

This is and oldie but a goodie!

Can you replace a polymer cap with a electrolytic cap and vise versa if the microfarad and the volts are the exact same? I ask because on the original xbox the same revision motherboards I have seen both for there 1500uf 6.3v caps

Great vídeo, tks Dave,..

why are you so happy?

hi What are the differences between polyester film and stacked polyester film?

nice job , easy to learn

Wow. Didn't know he's been on here so long.

you need 6 stars. Info is so exceptionel good. Thank you over and over again.

Watching this 10 years later... man, you haven't aged much!

One of the most detailed videos, I have not seen a more detailed video than this one, I am a novice when it comes to electronics, but videos like these is what novices like myself need to look at, only a few videos talk about esr and esl which is why I have understood why we use a ceramic capacitor, but I still not understood why do we use a capacitor, and if they are in parallel to the load them the load is getting twice the energy, amazing knowledge shared thank for being my guru just like another channel afrotechmod.

I'm a fan of your videos. I went back to this earlier video and what I really appreciate is your insight and experience. You hit on all the best aspects of capacitors in this video. Thank you.

How do you calculate the resistance value to go in parallel with series electrolytic caps. I thought you just picked a high value like 100k. I have 650vdc with two 47uf 450vdc in series across it. Thanks Duane

not sure why your CC are in Spanish haha

My new favorite word is DOJJY

Dave Jones is the name a so-called Microsoft Tech from India used when he called me to try locking me out of my computer so he can unlock it with a code.
