Hi Elso,

that was a good test. The big cap went up by about 5%. I got a similar result on a known mylar Wima MKT02i. Will test the small one later.

what about polystyrene? i have some caps which look like the polystyrene cap pictures i see online, but just want to confirm them. as i recall, polystyrene has a pretty nice TC curve...
if only it could be used for good, not evil...

can you explain me the difference between the different caps types? I've seen MKP, MKH, KP, and I don't know what this means, nor how good they are
Different kinds of plastic films have different properties. Sorta like different grades of iron, ferrite etc in transformers.
Some are dirt cheap.
Some make lots of capacitance per volume.
Some are very stable with temperature.
Some don't get hot at high currents and high frequencies.
Some are just plain unusual and expensive so you can kid yourself how much better the sound is with them.
Best-ever T/S parameter spreadsheet.

So, how good are the 0.1F MKH caps I purchased?
I searched on the forum, but I didn't found anything
it seems that no one here is talking about them

I think MKH was another name used by Siemens for MKT, i.e. mylar. Good for decoupling, bad for carrying audio signals.

BTW, i tried it with my caps, upon heating the capacitance did go down, so i guess their not mylar. it seemed like a large jump IMO, a minute under the dryer and the capacitance went from 40.3nF down to 39.9nF. well, maby just the odometer effect. the capacitance has returned to normal now.
if only it could be used for good, not evil...

Default article about caps

While we're at capacitors. There was an interesting series in Electronics World about capacitors by Cyril Bateman. It was in three parts around the end of the last year and the title was Capacitor Sound if I recall it correctly.

Could anyone help me to read the whole series by scanning in the original? I found only everyone referring to it on the net but I don't seem to get hold of the article.

TIA, regards
