Capacitors and inductors are fundamentally different in that their current-voltage relationships involve the rate of change. In the case of a capacitor, the current through the capacitor at any given moment is the product of capacitance and the rate of change (i.e., the derivative with respect to time) of the voltage across the capacitor.
The losses of capacitors are specified in a certain frequency range, and a lower loss indicates better performance. Aluminum Electrolytic Capacitors. Structural Characteristics: Aluminum electrolytic capacitors are formed by anodizing an aluminum foil to produce a thin layer of aluminum oxide (Al2O3) on the surface.
