For a demonstrator I am looking for about 10..20 Pulse Rated capacitors (photo flash, welding) of about 800..1500 uF, 300...500 Vdc.



Who knows a good source with reasonable price that ships to Europe?



With kind regards,

In the USA we have thrift/church stores where donated items are resold. They all have a shelf or box full of discarded film cameras with flash. Its very easy to extract the caps, most are 200 uF at 330 volts.

Can you gang up smaller photo-flash capacitors to reach the desired capacity?

has a couple of types for sale - 120 uF 330 Vdc for $0.99 each (take-outs from photoflash boards which were never shipped) and 100 uF 330 Vdc for $1.50 (unused). They do ship overseas to some countries ($50 minimum order).

Hello,

I thought that these were a niche product over here, but still several online shops sell them, so they are still alive.

Thanks for the hint.

This seems a good offer. If it is true what they offer (new old stock) it means you have about 1.4 kJ storage for USD 70 + shipping.

Just some slow reforming may bring them back to new state.

Info on overseas shipping is not fully clear to me, but some email will solve that I think.

thanks for the hint!
