They give coverage over a good range of frequencies. If some higher frequency protection is needed, add in a 0.001uF cap in parallel. For low frequency coverage switch to tantalum or electrolytic (tant is better but more expensive) of a value that depends on the low frequency current draw.Alexander Pope said:Whatever is, is right.
Thanks a lot, I like graphGenerally speaking bigger is better, but also costs more.
These are ceramic. Electrolytic are different.
I like that graph too as it shows bigger is not necessarily better.Generally speaking bigger is better, but also costs more.
