Re: Singing cap
Well, I didn't hear Rod Serling narrating the article or see a posting date of April 1 ... this is something I'd not heard of, though I think it's an aspect of the piezoelectric effect, which I have heard of. A changing voltage causes the ceramic dielectric to flex with the applied voltage, this, in turn, creates a signal voltage which can interfere with or distort the original signal.
This effect is more a concern in audio electronics. Switching P/Ss operate above 20KHz. If you work with audio electronics, go with film dielectric caps where possible - e.g. polyester, polycarbonate, polypropylene, polysulfone, polyphenylene sulfide.
I wonder if rap music might cause "singing" ceramic caps to crack ...PeteS in CA

by chth96I read EBOOK of Testing Electronic Component and found that
"In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."
Is it really possible to test small ceramic disc capacitor with analogue...-

I want to buy one of those SMD component books so I don't have to spend as much time searching my scrap boards for what I need, specifically ceramic caps and resistors as they seem to be what I spend most of my time replacing. But the only ones I can find are no name brands. Does manufacturer matter as much for SMD parts as it does with electrolytics or is the generic stuff likely to be fine?

by Wolf1977hi in ceramic oven the transformer is damaged
and writes
2x115v/2x12v/6VA 50-60hz ta105/f
can you suggest me a compatible transformer ;
i have found in 70 degrees celsius do you think is suitable for ceramic oven ; -
