    Hi!
    Why there is different size of capasitors with same values ?

    Depends on the type of capacitor, and also the voltage rating.

    no

    For example i have 2 radial capasitors and both these ratings: 16V 470uF 105C
    but one of them is 17mm high and diameter of 10mm in diameter
    and second one is 16mm high and dimeter of 8mm.

    The size of capacitors are continually becoming physically smaller as the dielectrics improve in them.
    Your question is probably in reference to different manufacturers capacitors.
    There are applications where a manufacturer needs a short, fat capacitor to fit in the
    chassis properly, or a tall, skinny capacitor to fit in some other physical application.
    Electrically, they're the same. The physical differences are due to manufacturer spec-
    ifications that they believe fit some industry need.

    different manufacturers?
    different years made?

    different materials were cheaper at the time

    There are tons of reasons this could be

    that explanes it pretty much.
    So there is no in a lifetime of these ?


    yes, different manufactures, and yes might be different years too.
    and different color.

    Remember when they told us a 1 Farad capacitor would have to be the size of a house?

    many things become so small they are impossible to fix.

    GonzoEngineer, I was in that high school class too.
    Teacher swore up and down that's what it'd take.
