What are the leakage current specification values for DC? | Capacitors FAQ | Murata Manufacturing Co., Ltd.
The leakage current can be estimated as follows from the insulation resistance specification value and the rated voltage of the item using the formula I = V/R. However, note that this is merely the value calculated based on the insulation resistance specification value specified by Murata, and only the insulation resistance item is guaranteed.
Capacitor Leakage Tester: What Is It and How It Works?
For the modern capacitor, we used the leakage tester to apply approximately 400 volts, and the leakage was around 25 microamps. That''s a small leakage, so the modern capacitor passed the test. On the other hand, we applied the same 400 volts to the old-fashioned capacitor, and we found it passing through 10x the current.

What is the "CV" unit for leakage current in a capacitor datasheet?
The actual leakage of an electrolytic cap may be much less than the rated value or a bit less. Chances are a higher voltage rated capacitor will have lower leakage when operated at a much lower than rated voltage, but it is not guaranteed, nor will it necessarily last if the capacitor is continuously operated at lower than rated voltage.. …
