    electrolytic capacitor different sizes with the same rating

    hello
    i am confused about something some times i see electrolytic capacitors with the same rating but in different sizes
    example
    1000 uf/ 250 VDC
    one small and the bulky as a can
    some does it mean one of them has more power ? if it is like that how can calculate power rating
    http://www.asianmicro.de/en/electrol...Page-2-50.html
    do you see in the site that big one ? it can be used as battery ?
    really im confused about that, sometimes i see websites tell it can be using capacitor as battery, but it could be that ?
    thanks

    Physically larger capacitors with the same voltage rating and capacitance as a smaller one will most likely be able to withstand a higher ripple current. This is particularly important in a power supply.

    Re: electrolytic capacitor different sizes with the same rat

    i am sking about something called "electrolytic capacitor bank" can consider it someknid of battery? and if so that, how can use it and how nuch power can supply ? if we use 4 electrolytic capacitor bank of 5600 uf/450 vdc as example

    electrolytic capacitor different sizes with the same rating

    You can put them in parallel to create larger values. It is not really a battery because the voltage will drop as you use the energy whereas a battery tends to hold a relatively constant voltage as you use them.
