An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
Let’s stick to the topic of polarized electrolytic capacitors. An electrolytic polar capacitor is a type of polar capacitor which has polarity on its terminals denoted by cathode and anode (positive and negative terminals).
Capacitor polarity refers to the orientation of positive and negative terminals in a capacitor. In polarized capacitors, the positive terminal (anode) and the negative terminal (cathode) must be connected correctly to ensure proper functioning. Conversely, non-polarized capacitors don’t have this restriction and can be connected in any direction.
When working with electrolytic capacitors, it is essential to keep some key considerations in mind to ensure their optimal performance and safety: Polarity: Due to their polarity, electrolytic capacitors must be connected in the correct direction in a circuit. The terminal with the band or mark usually indicates the negative terminal.
Electrolytic capacitors use a chemical feature of some special metals, previously called "valve metals", which on contact with a particular electrolyte form a very thin insulating oxide layer on their surface by anodic oxidation which can function as a dielectric. There are three different anode metals in use for electrolytic capacitors:
In case of reverse voltage (negative source to positive terminal and vice versa) will blast the aluminum electrolytic capacitor due to the hydrogen ion theory. In this wrong wiring connection, there is positive voltage across the electrolytic cathode and the negative voltage appears across the oxide layer.
