[sdiy] The best types of capacitors to use when designing a VCF

[David G Dixon]

I use silvered mica for VCOs and VCFs, typically 390pF or 500pF.  They work
very well.  They are typically big brown things that are kinda lumpy.
 
You have to be careful with some types of caps, such as polystyrene, because
they are easily damaged or destroyed when soldering.  Not sure about
polypropylene.  Silvered mica and metallized polyester are pretty forgiving.

If you can afford them then polypropylene are the very best you can get for
pro-audio.   But a good metallised polyester isn't far behind.

 

That said, for many products automotive quality SMD ceramics (the ones with
the anti-vibration mountings that kill microphony) are more than good
enough.

 

There's a whole chapter on choosing components like this in Douglas Self's
book which it is well worth buying a copy of.

Hello.

 

Can anyone tell me what are the best types of capacitors to use when
designing a VCF ?
