What Caps?

Hi,

Got a axial capacitor of 23VAC, 3.3microFarad X11, bipolar- GPF by WEGO
ELKO glatt W. Germany. Measured D=10mm L=25mm and used in a M/Benz car
rear speaker system for the tweeters.

Requesting help on sourcing a replacement parts for it. Could a normal
electrolytic caps work as well though has polarity to it.

Any insight and or leads is greatly appreciated.

Thanks a million!

Nonpolar electrolytics are easy to find, you just need to look the right
places. Try Parts Express or MCM, they both have a fair amount of audio
stuff. Higher voltage rating is fine just so long as the capacitance is
close.

IIRC, you can use two polarized caps (each TWICE the target value) wired
series back to back to replace an AC capacitor like thus:

------|(-----)|-----
+ - - +
6 mf 6mf

(to replace a 3mf ac cap)

Someone coreect me if I'm mistaken.

You need to use 2 polarized caps in series (as another poster pointed out)
or a single bipolar for crossovers (I can;t remember why though - anyone?)

I would think about replacing this with a polypropelene cap -
electrolytics sound pretty bad, and shame on Mercedes for using them
in their crossovers - Tim

Thank You to James and Stan for the inputs. I finally got hold of NTE
website and found they do have a NPA series (Non Polar Axial) type of
caps. I will check them out tomorrow with the local distributors!

Thanks a million to you both! ;-))

Have a pleasant day!

You can easily find non polar caps at most electronic suppliers. You will
not easily find 23 Volts. You can use a 25 volt or higher rated for the
voltage.

Another solution is to take 2 of 6 uF / 25 V standard caps and put them
back to back. Put the two minus sides together. I personally would use 2
of 10 uF / 25 V back to back, because when doing this there may be some
loss, and the 10 uF is a common value that you will find. The precision is
not very critical. Most of these caps have a 20% average tolerance for their
microfarad rating.

Hello,

Thanks to ALL for your constructive inputs. Today I manage to get a 3.3
microFarad 100V(!?) Non-Polar (non branded?)caps. It works! ... but felt
that a 35V to 50V would be better suited for the circuit (frequency
responds) in lieu of the original 23VAC. Oh well, am a happy camper
again!;-))

Again, thanks for all your help and advice.
