Due to size constraints on a custom PCB , iI have opted out for using the smallest type of Electrolyticelectrolytic capacitors ( 33 mm diameter ) .) However , capacitors in such a small diameter are almost impossible to find.
If iI remember my high school books correctly , tantalum caps are actually a type of electrolytic capacitors just with different purpose and their size to capacitance ratio is much better than the electrolytic ones.
I know that they have other advantages, but my biggest concern is is it possible to just use Tantalumtantalum capacitors instead of ordinary Electrolyticelectrolytic capacitors ? The circuit in mind is just an ordinary amplifier for an electret microphone using a simple LM386.
Edit : hereHere is the schematic, iI am asking for all the electrolytic capacitors.
