Re: 求教

Using Rubycon datasheet as reference.

Leakage Current = I
E.g. 1000uF / 16V

I = 0.01CV

Where C = Capacitor value (e.g. 1000uF)
V = Rating voltage = 16V

I = 0.01 x 1000u x 16
= 0.16mA

Suggest measure the actual value by connect the power source atleast 2 minutes.

Actual figure is << than calculating value.
