Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as "electrolytic capacitors" or "electrolytic capacitors", are one of the most widely used and commonly used electronic components. Generally, this type of capacitor consists of an aluminum foil on which a very thin oxide layer (called a "dielectric") is electrochemically formed, and a paper impregnated with an electrolyte is wound as an anode. A metal case seals the anode and the oxide layer is then a cathode. When a voltage is applied to the capacitor, the electric charge on the metal oxide layer forms an electric field, thus creating a capacitance between the two electrodes.

ESMG351ELL2R2MHB5D Application Field and Working Principle

The ESMG351ELL2R2MHB5D aluminum electrolytic capacitor is a small-sized, high-reliability capacitor with a wide range of operating temperature (-55℃ to 105℃). It is an ideal choice for use in various types of electrical and electronic equipment. The capacitor has a paper cathode and a copper-clad aluminum anode, which is firmly sealed by a aluminum case. The case is also protected by additional insulating and oil-resistant materials. The dielectric oxide layer, formed by an electrolytic process, is a thin film with excellent characteristics such as high breakdown voltage and low leakage current.

The working principle of the aluminum electrolytic capacitor is very simple. When a voltage is applied to the capacitor, positive ions in the electrolyte are attracted to and form a parasitic electric double layer between the electrodes (anode and cathode). This structure forms an electric field in the dielectric layer. The magnitude of the current through the capacitor is determined by its capacitance and by the voltage that is applied across it. When the voltage is reduced, the current is reduced and the capacitance decreases, thus providing the desired capacitive properties.

The characteristics of the ESMG351ELL2R2MHB5D aluminum electrolytic capacitor make it a particularly suitable choice for use in high-temperature environments, such as in power supplies, automotive applications, and medical equipment. It provides good performance in high-frequency applications as well, and is suitable for use in circuits experiencing rapid temperature changes. Additionally, the capacitor offers low equivalent series resistance (ESR) and low self-inductance, which make it suitable for pulse applications.
