[sdiy] Making a NP electrolytic out of two Polarized caps?

[Ray Wilson]

Hi

You got it right. Tie the negative ends together (I think this was a Craig
Anderton tip). When you put caps in series you decrease the capacitance in a
manner similar to the formula for putting resistors in parallel (if you get
my meaning). In your case you will need to put two 100uF caps in series to
get 100uF. But this begs the question... why don't you just buy some 100uF
non-polarized caps?

Hello,

I'm after a non polarized 100uF cap or higher value.  I heard that you can
make one from two electrolytic caps, but the position and value to make
100uF eludes me.

I think you tie the caps in series at the negative lead, but I really don't
know.

Any help greatly appreciated.

Thanks

Ed
