Filter capacitors play a critical role in ensuring the quality and reliability of electrical and electronic equipment, especially memory devices and computers (1, 2).Circuit filtering has been dominated by aluminum electrolytic capacitors (AECs), which, unfortunately, are always the largest electronic component owing to their low volumetric capacitances (1, 3, 4).
8.2: Capacitors and Capacitance
A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...
