Understanding Filter Capacitor

A filter capacitor, also known as a smoothing capacitor, is used in electronic circuits to filter out unwanted signals or voltage fluctuations and provide DC put out smooth. Filter capacitors work based on the principle of capacitive reactance. Capacitive reactance is a capacitor''s opposition to the flow of alternating current (AC).

Electrolytic Capacitor Schematic Diagram

In an electrolytic capacitor schematic diagram, the main components are the capacitor, the cathode (negative terminal) and the anode (positive terminal). A typical capacitor is constructed with two metal plates that are separated by an insulating material, known as the dielectric. The dielectric determines the amount of electric charge that can be stored in the
