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

2 years ago I bought a brand new 50 watt all tube Marshall amp JVM 215C. I couldn't use it for a few months. But when I turn it on it started crackling which I guess is a typical sign of the capacitor It took him five weeks to figure out it wasn't tube or a resistor. It was a "silver mica" capacitor. He said it's rare for one to go out on a new amp but it did. Now that it is fixed, it sounds like new. Thank you for this video it's thorough and informative. 🙏🕊️❤️

Love your channel. I know this is an old post, but had to comment. When you described the ceramic as very dependable and rarely fail I had to laugh a bit. In high school in the 70s I worked in a radio and TV repair shop. One of the first TVs I repaired in the shop had no audio. Guess what it was... A ceramic cap had shorted! I know it's rare, but it had no visible damage and yet tested as a direct short. That was a fun one. By the way, the shop was in SW Virginia where a lot of folks heated their homes with coal. Still saw a lot of tube TVs... There would always be a coating of coal dust all over the HV sections and CRT.... Made for some fun troubleshooting as the coal dust is conductive and the HV would find its way all over... The light show inside these TVs was quite pretty! Lol 😂

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

Ultra old school! Why, you whipper-snapper, if I wasn't retired I'd give you such a talking to! Ultra old school was field coil speakers and radio dials that went from 0-100. 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!

I am sorry but no mention of electrolytics? I have some old Heathkit kits that have electrolytics. I assume, since they are decades old, have gone bad. Thanks for an otherwise great vid on caps.
@spartan4567 жыл бұрын
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.

Thanks for reminding me they're aluminium canned paper jobs. So would I be mad to try and replace all aluminium electrolytics that I maybe replacing anyway (for example power supply) with poly or tantalums, ignoring expense and availability of farad capacity?
@spartan4567 жыл бұрын
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.

Thank for the clarification Mr. C. Been a hobbyist for many years and that was a great tutorial. Seeing it as well as reading it really helps to reinforce the information.
