Introduction to Aluminum Electrolytic Capacitors

An Aluminium Electrolytic Capacitor is an electronic component made of two aluminum electrodes designed to store electrical energy. The Aluminum Electrolytic Capacitor is a dielectric capacitance component that utilizes the significant dielectric properties of electrolytic medium (material) between two electrodes formed of aluminum and its derivatives. The two electrodes are connected with the help of a dielectric medium made of organic solvent. The electrolyte is held between the two metal plates or electrodes and prevents the current from flowing through the component, thus providing the capacitive action.

MAL212855109E3 Application Field and Working Principle

The MAL212855109E3 is an Aluminum Electrolytic Capacitor designed to be used for power supply require high-capacitance, low-resistance, and high-density applications. It is especially suitable for solar inverters, UPS, power supplies, industrial equipment, and numerous other areas such as small household appliances, automotive and home audio systems. The MAL212855109E3 is a large capacity type capacitor that features a working temperature range of -55℃ to +105℃. It is made of a 20% Proprietary Aluminum Nitride (AlN) and a robust low-DF (DF < 20%) Impedance design to reduce ESR (equivalent series resistance). The MAL212855109E3 is also qualified to the MIL spec.

The MAL212855109E3 is a polarized Aluminum Electrolytic Capacitor with a long length constructed with patented manganese dioxide electrolyte. This electrolyte has a higher oxidation and reduction potential than conventional electrolytes, resulting in a much higher temperature coefficient. This enables the capacitor to withstand up to 105℃ of continuous operation in the temperature range of -55℃ to +105℃. The MAL212855109E3 also features an improved axial lead form factor for space saving and cost-effective mounting.

The working principle of the MAL212855109E3 is simple. The capacitor is constructed with two aluminum plates separated by a dielectric material (most commonly organic solvent). When a voltage difference is applied across the two plates, the charges created in the electrodes due to the dielectric materials. This then produces a capacitive current that can be stored within the capacitor for a period of time. The capacitive current is then discharged when the power is removed.

Conclusion

The MAL212855109E3 is an Aluminum Electrolytic Capacitor that is suitable for power supply, solar inverters, UPS and other high-density applications. It features a working temperature range of -55℃ to +105℃, and is constructed with patented manganese dioxide electrolyte and low-DF impedance design to reduce ESR. The working principle of the MAL212855109E3 is based on charging and discharging of capacitive current within the capacitor plates when a voltage difference is applied.
