I'm building a circuit (Catalinbread DLS) that specifies a 0.22u electrolytic in part of the circuit that (i think) rolls off some low end, but i can't source that particular value of electro.
Is it vital the cap is polarised? (link to layout is below) I could swap in either a 220nF polybox (obviously unpolarised) OR sub a couple of 100nF tantalums that are polarised, albeit 9% too small in capacitance. And, on a more general question, when (or where) are polarised caps vital in circuits? I know higher value caps tend to be polarised, but i always assumed this was a function of their construction, i.e. higher value caps have to be polarised to allow higher capacitance values, or something. Please excuse the noob Qs.

I would use a 220nF box cap. In almost all cases, you can substitute a non-polarized for a polarized cap without trouble.
