Well I'm looking for a pair of 450V 220uf caps in series for 670 volts. I found a CDE in 30mm X 30mm at $3.60 each. I would rather have a Nichicon UC* series, but they don't come in 30mm wide for stuffing into old aluminum caps, and don't get above 120uf in 16mm wide.
Wonder if these are available in Sweden?! Have to get started on some old projects lying around. 500V would also be fine, as I am to filter 700V, and in series is perfect.
