Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, sometimes known as aluminum electrolytic capacitors, are a type of capacitor that uses an aluminum oxide as a dielectric medium. It consists of two aluminum foil electrodes, a piece of paper or other dielectric substrate, and an electrolyte. The aluminum foil electrodes are known as the anode and cathode, respectively. Aluminum electrolytic capacitors are often composed of tantalum, niobium, or permalloy and are often referred to as "electro-chemical" capacitors.

The aluminum electrolytic capacitors of the type MLS112M075EK1A have a wide range of application fields due to their low cost, high capacitance and low ESR. This type of capacitor is frequently used in the following applications:

• Power supplies, inverters, switching power supplies, wireless charging, pulse applications, switching mode power supplies, electric vehicles, medical electronics, electric bicycles, solar energy.
• Motor drives, bridge circuits, clock circuits, rectifier circuits, pulse circuits, inverter circuits, snubber circuits, synchronous motor applications, controllers, power factor improvement applications, and many more.
• TV sets, computers, audio amplifiers, display boards, microwave ovens, household appliances, electronic toys, phones, video equipment, automotive electronics, antennas and game consoles.

The working principle of the aluminum electrolytic capacitor is based on the electro-chemical reaction between an aluminum foil and an electrolytic solution. When a positive charge is applied to the foil, the aluminum ions move to the negative electrode and release electrons, creating a current flow. This current flow creates an electric field in the capacitor, a stored energy which is later discharged when the charge is removed from the capacitor. The capacitance of the capacitor is a function of the thickness and area of the aluminum foil, the dielectric material, and the electrolyte.

Aluminum electrolytic capacitors have the advantage of being able to provide higher capacitance than other types of capacitors. They also can withstand higher temperatures than other types of capacitors and are therefore widely used in high temperature applications. The main disadvantage of aluminum electrolytic capacitors is that they are prone to leakage and they are not particularly reliable. Due to this, they are not suitable for operations in which high reliability is required.

In conclusion, the aluminum electrolytic capacitors are relatively low cost and have high capacitance and low ESR, and thus they have a wide range of application fields. However, they are prone to leakage and have low reliability, therefore they should only be used in applications where reliability is not a requirement.
