Capacitor Leakage datasheet confusion

shawnmk123 · Oct 11, 2014

Hello,

I was going through this part on digikey
https://www.digikey.com/product-detail/en/KR-5R5V474-R/283-2815-ND/1556243

the ESR is 40 Ohms. The datasheets says that the leakage is low.

Is this because the ESR is high ---> current is low?

You are talking about two unrelated properties. Leakage is caused by a parallel resistance, ESR is a series resistance.

If the plates are very closer the leakage will be more. yields you more capacitance value.
if the plates are too thinner then the ESR will be high. gives a compact size.

But there is no relation between this two.

For a smaller sized capacitor these both will be in the worst case.

both of you gave helpful responses.

thank you
