Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are passive electronic components with an inherent dielectric. They are usually characterized by large capacitance values per unit volume, low cost, and long operational lifetime under continuous usage. Aluminum electrolytic capacitors have two distinct elements in their construction — aluminum foil and an electrolyte. These two elements, when combined, offer much lower equivalent series resistance (ESR) and less stray capacitance compared to other types of capacitors. These exceptional characteristics result in significantly higher efficiency in power conditioning applications, such as power amplification.

MAL202190524E3 Application Field and Working Principle

The MAL202190524E3 aluminum electrolytic capacitor has been specifically designed for high-current applications such as electric motors, uninterruptible power supplies, solar inverters, or welding equipment.

The MAL202190524E3 features an axial-leaded, non-solid aluminum electrolytic capacitor with an 85 °C maximum working temperature and a maximum rated voltage of 450V AC. The capacitance of the device is 220µF, with a tolerance of ± 20%. The lifetime expectancy of the capacitor is up to 5000 hours.

The MAL202190524E3 is constructed with a simple design. It consists of a thin aluminum foil etched with a pattern of evenly-spaced rectangular shaped "voids" through which the electrolyte can pass. One or two layers of insulating material (paper or foil) are then placed on top of the aluminum foil. This is then inserted into an aluminum tube, with two electrical leads protruding from each side. The electrolyte is then injected into the tube. The electrolyte will cover the electrodes and fill the voids in the aluminum foil. The result is a device that behaves like an electrical capacitor.

The primary purpose of the capacitor is to store electrical energy. When the capacitor is connected to an AC power source, the alternating current passes through the electrolyte, causing the charges to move between the aluminum foil and the electrolyte. This creates a current flow, which in turn stores up electrical energy between the two plates. This energy is always released when the device is disconnected from the power source, which then causes a current to flow through the load.

The MAL202190524E3 is a non-solid aluminum electrolytic capacitor, meaning that it requires regular maintenance in order to maintain its performance. The electrolyte should be checked and changed regularly to ensure that it is doing its job and that the device is performing as expected. This is also important to ensure that the capacitor is not damaged by overheating.

In conclusion, the MAL202190524E3 is an ideal choice for high-current applications such as electric motors, uninterruptible power supply systems, solar inverters, and welding equipment. With its robust design and reliable construction, the MAL202190524E3 is the perfect choice for any application requiring reliable power conditioning.
