Hi Mick, in other words Mica silver or Mica capacitors have the same effect as piezo materials, what is cog? Because I with low frequencies work do I need already capacities in uf area. Under Mica can I find what. Greetings Sven

Sven,
Anytime one adds more capacitors Q drops as ESR increases so it
works better if one can use the piezo for both functions, if
possible. Many capacitors are also piezoelectric materials such
as the mica and COG. Lower frequencies do not matter as much.

Hi Mick, so I could try in addition to the caps piezo
elements for this purpose to turn, there is there an
increase of the q value or did you only with piezo worked?

Hi Sven
Yes I have used the little piezo transformers and have
also used disks in a tank circuit acting as the
capacitance. On the transformers I was able to get the
most gain by using sine waves as they like a clean
signal without distortion components being of high Q at
the designed frequency. Something I need to get back to
in order to determine more facts.

Hello
Mick,
Many thanks for the hints, unfortunately I
can not find distribution in Germany or I have
to search again.
Have you ever included piezo elements in a
reactive circuit?
regards
Sven

Hello
everyone, is it possible
to use resonant capacitors
in the case of FR
transformer in addition to
switching piezo elements
in parallel or do the thin
elements hold over 400V?
The MRA of Norman
works with a large piezo
element, unfortunately I
can not get something like
this or I search wrong via
google.
