Hi Steve,
1700uF is quite a non-standard value. Have you considered connecting in parallel two or more similarly rated capacitors to obtain the 1700uF? You should be able to “dial in” a capacitance very close to 1700uF. Or is it your intention to utilize only a single capacitor? Anyway, IHTH. I look forward to your reply.

I’ve found several capacitors that meet some of the criteria but not all. The parameters are; capacitance, voltage rating, tolerance and ESR. The closest value capacitor I was able to find was 1500uF which met all of the requirements. I had considered purchasing three or four of those, hoping that at least one would run on the high side and measure at 1700 +/- 20%. Obviously, I would prefer to locate a single capacitor with the advertised specifications that meet the requirements per IEC 61000-4-11. Any help would be appreciated.
