First of all I'd like to say that I'm quite new in electronics (I'm a software developer) so I might be missing some basic knowledge for which I apologize.
I'm trying to create a DAC using the PCM5122. The datasheet mentions that the charge pump flying capacitor should be a 2.2uF COG Ceramics (I'm guessing COG should be C0G - C zero G).
Now, I've been to my local electronics dealer and he has never heard of a ceramic capacitor with that value. Also Conrad (where I usually get my stuff) doesn't have one. The only place where I can find such a capacitor (SMD) is at Mouser (which will cost me € 20,- on shipping).
My questions are:
- Why is this so rare?
- Is there a non-SMD variant of this capacitor (I can't find one but maybe I'm not using the correct search terms)?
- Can I use something else in stead?
