After blowing up a tantalum capacitor by inadvertently connecting it the wrong way round, I thought I'd investigate high value multilayer ceramics.

Excelente tengobun multimetro fluke que tiene unos capacitores de tantalio,polarizados y los e retirado y comprobado con un multimetro analogico en su carga y descarga y efectivamente no funcionan una esr,mal
I've started my journey into the world of electronics and the first question I have is how can we find the values of a multilayer ceramic capacitor that is shorted without schematics??
Tantalum is a conflict resource anyway, so another good reason to go with ceramic instead.
I had a very old PC motherboard and one of tantalum caps just explpoded.
They make the small blue disk high voltage cap.
NO need to look into it ceramics move like crazy the heat of your hand will make a ceramic move this is why they are not suitable for oscillators or timing circuits only bypass and stuff like. The exception to this is the NP0 ceramic but they are generally low value and not as cheap. Really good video is Mr. Carlsons which capacitor does some very interesting experiments with drift. On GenRad damn this video is old my bad
Nice
Non polar capacitor as the ceramic and the tantalum cap id polarized so
Ceramic is microphonic, so it's not suitable for audio related application, or anything where that would be an issue.
tants are crap
Tantalum are also very sensitive to the wrong polarity. Electrolytics are a bit more robust when installed backwards. I have never actually destroyed one, whereas I have destroyed a few tantalums in the past due to incorrect installation. This happened under light loads, well below their max voltage rating. They never did anything dramatic. They just stopped working…. It might have just been bad luck, but now I try to avoid tantalum.
This is not correct. It was the price of palladium that drove the innovation to base metal electrode MLCC. Tantalum encroachment was just a side show of the war. It was first used in consumer audio and video imaging equipment in Japan; but made its huge leap in notebook computers, handsets were once again- a development of that war.
Sir, can I use ceramic or electrolytic capacitor for the nrf24l01+ module , to resolve the battery problems??
Did you ever resolve this ? Is there another part to this video ?
To get such high capacity in such a small package, ceramic capacitors use ceramic with a very low stability. I think they exhibit a positive going value with a upward rise in temperature, I'm not sure, it could be the other way around. Tantalum caps don't have such great temperature coefficients and are therefore more desirable in applications where things are a bit more critical with regards to the exact value. Have you ever noticed how much bigger NPO ceramics caps of a certain value and voltage tend to be than their less stable counterparts?
