Can I make a Non-Polar Electrolytic using two polar ones

PaulHilgeman · 9th February 2003, 08:13 PM

Can I just hook them up in parallel with the inputs switched? Of course using half of the value for each one?

in series........ either + connected to + or - connected to -

I have seen them put in series with the minuses connected together. This would halve your capacitance.

yep, in series, but make sure to use double the value for each one.

Thanks alot!!!

You have to connect them in serie. Non polarized caps are simply two polarized in serie. An elctrolitic is a resistor (a BAD resistor) if you connect it inverse. It's better if you use a paper & oil capacitor.

Connect them back to back (minus) to get half the capacitance, but it is advisable to ground that connection with a 100k resistor for a typical audio application.
