Rectangular and triangular signal generator.What application?
MKP4 maybe.

Thank you. I have one more question. Ceramic capacitor doesn't work at high frequencies ?Mica, Ceramic.

800 Hz isn't high frequency. Ceramic caps work well at much higher frequencies.Ceramic capacitor doesn't work at high frequencies ?
Modern ceramic capacitors work extremely well at high frequencies and as general purpose capacitors in most applications.. Some of the older types like ceramic tubular capacitors and barrier layer capacitors are obsolete today because of their size, parasitic effects or electrical characteristics.Thank you.

So, it's good to choose a modern ceramic capacitor for my application ?Modern ceramic capacitors work extremely well at high frequencies and as general purpose capacitors in most applications..

Depends upon if temperature variation in capacitance value affects critical circuit operation, which you haven't specified.So, it's good to choose a modern ceramic capacitor for my application ?
This is a very important (bad) characteristic of Z5U and X7R ceramic dielectrics, especially for ramp generators and timing circuits. I believe NPO dielectrics are much, much better. Hence, the recommendations for NPO. It is a great link. I have never seen a clear explanation of why high dielectrics are so bad with this spec. The voltage coefficient of capacitance is very low for polypropylene which makes them good for high accuracy timing.A downside of Ceramics, certain types (C sensitivity to its terminal V) -

Are you over-thinking this? What's the worry?Hello ! What type of capacitor is a good choice to work at 800 Hz, voltage 12-15V and nominal capacitance around 24 nanofarads ?
I would be surprised if a ceramic capacitor was a good induct or at 3 MHz.I am playing with NanoVNA today and fell in the shock HOW BAD are the most of smd capacitors. All my 0,1 mkF caps turned out to be the good inductors as soon over the 3 MHz when I am using it being the Vcc capacitors. Warmly suggest, if any doubt about a certain capacitor, apply the NanoVNA or at least SA1201, yet the last works only OVER the 137 MHz up to 2700 MHz. There are a drastical price reduction on all e-bay shops for a moment, seemingly because of the pandemy.
