Love your work ! Where do you buy your replacement caps? I can find any place locally that sells components :-( HELP ! Thanks.
@hairypaul34576 років тому
Many years ago I was involved in developing sensitive alarm systems. We utilised the Piezo-electric effect of ceramic caps for vibration detection as part of an 'anti-tamper' warning sub circuit. Our ceramic cap piezo-detection circuit was much cheaper than the vibration detection devices used in previous systems and they turned out to be much more reliable, I believe there are still several of these alarm systems still in 24hr use today over 25years after installation. Sometimes the normally 'unwanted effects' of components can be put to good use. :-) Many thanks for these videos Paul. Keep up the good work Sir! 73.

Thank you for your videos. I've been an electrical and electronics hobbyist since 1964 when I was 10 years old. I destroyed my family's toaster when I took it apart out of curiosity. My parents bought another one and also bought me some tools and other second hand electrical things from a second hand store to pursue my interests. Later I got into repairing stereos, CB and other radio equipment, and designing electronic gadgets, like a signal system for model trains. I do enjoy your videos as I can always learn something from them.

Excellent overview and tutorial for someone starting out. There is one application where I always replace ceramic capacitors. Old tube type CB radios often used either a dual section or two separate ceramic caps as line to ground safety caps. They are in service all the time since they are connected directly to the mains input they live a hard life. I have seen several of these plain blow up and flame out. I just uploaded a couple videos yesterday and today on a customers Tram D201 I restored and went over why the ceramic dual section bypass cap should be replaced. I use modern X1 / Y2 rated caps (the blue disc type) for line to ground and also add a X2 rated one (yellow box type) across the line for some additional filteting. Ever run into silver migration problems in the old mica mold caps. I did once and it drove ne nuts tracking down the culprit. Mike

+MikesRadioRepair .CBRadio Hi Mike, I have run across silver mica disease in some AA5 IF transformers. I use those 1206 NP0 parts displayed in the video as replacements. Those old Tram radio's are pretty neat, I have one as well, somewhere around here. Thanks for the kind comment!

I'm just now getting started back in electronics from a class that I never got to complete just 1 semester on but I knew instantly that it was the only thing in school that I ever liked, besides the early math. So from the late 70's I guess it's about time I get the chance but only from a disability, so I'm learning a lot from your films, so don't give up on them.

Paul, Very good explanation of the various capacitor types. Don't have any horror stories about tantalum caps, but in my youth we had some (temporary) fun making paper caps explode like firecrackers. That was definitely an extremely dangerous stunt that should not be done. Still have a scar on my forehead where one of the capacitor leads impaled itself. If it was one inch lower, and I had removed my glasses, I would have lost sight in my right eye. The high school lab instructor was not pleased and we ended up with a weeks worth of detention.

This video deserves a million likes instead of some stupid kid smashing a grilled cheese on his face. When faced with the multitude of choices on DigiKey this gives you a great way to get to the perfect part. How about a video on electrolytic caps, trade offs for tolerance, high temp, and so forth, I've seen some with super lifespans and have not ordered them just chose a good brand matching basically what was originally used. I've always wondered if you were to recap a receiver completely with the extremely long life ones if other properties of the part would be an issue. I have one project from the 70s I havent torn into yet but it's a very nice unit and when I tear in I would love to design the boards to last 100 years, maybe it can live through a couple generations in my family, I'm pretty sure there are some downsides to the properties of those that would make them not the best choice
@gsansoucie6 років тому
If you had told me that I would spend 24 minutes watching a video about capacitors this morning, I’d say you were crazy. I figured I’d watch the first two minutes and move on. This was an excellent video, while I don’t see myself designing circuits (I will copy them), this knowledge is useful in practice. I would like to have seen some segment on the leaky effect of the paper caps too, something to back up your claim (although I don’t doubt you).
@douggwyn96565 років тому
Just check the DC resistance between the capacitor terminals. If the capacitor is not leaky the resistance will be high (tens of megohms at least), whereas if the capacitor is leaky the resistance will be much lower.

What would be the best choice for replacing basic through hole electrolytic capacitors in video game systems such as Sega Genesis,NES,and SNES?

Just caught this (after two years!). Good demonstration, but I wish you'd covered more than just polypropylene (& polystyrene) films. I think the public would be well-served to understand the strengths and weaknesses of the various film dielectrics, including polycarbonate, polyethylene (/PET/PEN/PPS), Teflon, etc. Perhaps a "Part 2" specifically on film caps? I noticed "Raindrop Services" asking for it (about a year ago) as well.

@pliedtka4 роки тому
Yes, it is a good idea. People think that some capacitors have some magical properties, say Teflon, or silver foil in oil, or Clarity Cap being better than Solen, so to bust the myths and give us guide what actually works properly in given circuit would be great idea for a video. I read stories, say, where Wima MKP supposedly sounds better than other brand, but I don't really buy it, and if it really does what's the reason for it (maybe accidentally polarity was reversed).

When you found a station you liked you wrote down where it was - tune in 37 for news and weather. And I'm not buying a hearing aid because they don't make any with loctal tubes - all the octal tubes fall out when I dance. When I got in to General Aviation (small aircraft) avionics in 1970 most of the equipment we worked on was hybrid - some transistors (at least in the power supplies and audio) and some tubes. By 1980 I don't think there were any tubes in the new equipment, and ICs (small scale) were appearing. Technology moves faster now!

To be fair, he kind of covered those when talking about the paper and foil caps. Electrolytics are the same thing, just paper and foil and the paper is soaked in an electrolyte. It's not that they're inherently bad, electrolytics do serve a purpose, particularly in achieving higher farad values than polyester or ceramic ones.

@spartan4567 років тому
Tyeth Gundry Yes and no. There are some benefits to using electrolytics. Capacitors are more than just things that can store an electrical charge, and the makeup of them determines their overall activity in a circuit. Electrolytics are super common in power supplies for smoothing out ripple, which you'll want to achieve a smoother output voltage. I can't speak for ceramic or tantalum capacitors as I do not know enough about their major usages, but I know for a fact you'll find more electrolytics in high-voltage filtering applications than the other types, like in power supplies and amplifiers. That might be something you can do as a little fun project. Build your own power supply and test the outputs with different kinds of capacitors. You'd need a scope but I think the results would be interesting.

Electrolytic capacitors lose their capacity over time, even when just stored. At the same time they remain as much as big and weight as much. But they still can be used, though not in the most efficient way.

Thanks! Just looking/learning.

Thank you! That was a super interesting and informative video! Some other ideas for you: 1. Testing components in situ. 2. Type of components and component preservation strategies used is extreme environments (e.g satellites, space probes, mars lander). 3. How to build an inexpensive solid state low watt, low THD audio amp for testing and comparing the tone of guitar pedals.

I'm embarrassed to say that I had no idea how unstable ceramic disc caps were with temperature. Wow they're bad!
@Gooberslot7 років тому
Well, he did say that that was a particularly low quality cap. A high quality X7R would probably do better.

Gooberslot But nowhere near an NP0 ceramic cap.

You have revealed an unsuspected hole in my technical training, and given me a good start in patching it. Many thanks.

Excellent video comparing specified performance with actual measurements. Very well presented. Thanks for putting this together.
