  • Hi Mr. Setsuda.

    I'm evaluating EECRF0H104EECRF0H104 Gold CAP. I want to charge this CAP with a battery (4.2V).

    1) On panasonic application note I read: no need of any external resistor because all internal capacitances have to charge and there is many internal resistances, one for any capacitance element. But at the first time, with cap completely discharged, what is the current taken from battery (I suppose to connect CAP in parallel way to battery )? Is there a particular note to connect it to battery?

     

    2) Now I suppose CAP completely charged and my battery is very low and I suppose a pulse current with very low intensity (150 uA every second). Is EECRF0H104EECRF0H104 choice correct? Is Gold cap lifetime destroyed by such current pulsing load?

     

    Thank you very much.

     

     

    Thanks a lot
