What is the maximum current for the common electrolytic capacitors?

Question

I want to use parallel capacitors to support more current in a switching mode power supply circuit so I need to know how much is maximum current for one common electrolytic capacitor?

Answer 1

From Nichion datasheets.

22 uF 6.3WVDC -- 85 mA ripple 120 Hz

1000 uF 6.3V -- 540 mA

33,000 uF 6.3V -- 3.8A

22uF 50V -- 95 mA

1000 uF 50V -- 1.35A

10,000 uF 50V -- 4A

Go to the manufacturer's website and look up specific numbers for your specific capacitor.  The thing you are looking for is the 'ripple current' rating.
