A capacitor is a passive two-terminal electrical component that stores electrical energy in electric field which combines with the magnetic field to form the elecromagnetic field, whereas filters are circuits that perform signal processing functions specifically to remove unwanted frequency components from the signal, to enhance wanted ones.
You might know that capacitors are vital part in every electronic device. You might also know that without capacitors you would not be able to filter frequencies and signals. In addition to that, the technological advancement, which made computers present in every office and every house, made also their electrical components fundamental in the industrial world. In this spectrum, the manufacturing of capacitors has become irreplaceable.
Concerning that, if you are in search of electrical capacitors suppliers all over the world, enjoy a free registration in e-electricity and find out a full list of capacitors and filters manufacturers.
