This is more a theoretical question.
I have a DC circuit with multiple capacitors with different voltages. Because I need to know how much current my circuit needs over a longer time, I calculated all the capacitor leakage currents which are around 0.8 uA. When measuring the current of my device while running, I only have around 0.3 uA. It was measured with a uA Multimeter in series with the DC source.
For the calculation of the capacitor Leakage currents, I used the given values in the datasheet at room temperature.
My question now is:
Why is my current so much lower than my calculated value when measuring the circuit? Are the values in the datasheet more suggestions or how am I to interpret the insulation resistance?
Unfortunately, I am not able to provide any schematics for this question.
