Aluminum electrolytic capacitors are a type of capacitor widely used in electrical equipments. They are characterized by superior performance, high efficiency, and high reliability. EEU-TA1H220BJ is an aluminum electrolytic capacitor with a tolerance of ±20% that is able to support high working voltage.

An aluminum electrolytic capacitor consists of a solid aluminum outer casing, electrolyte, and two aluminum foil electrodes with a dielectric layer in between. The positive electrode is layered with an aluminum oxide film that enhances its capacitance. The electrolyte is usually composed of a solution of sulfuric acid or a solid form of hexafluorophosphate. The combination of these components creates a high-capacity, effective device.

EEU-TA1H220BJ capacitors are mainly used in audio equipment, personal computers, instrumentation equipment, and LED lamps. In audio equipment, they are used to reduce noise and smooth out current fluctuations. In personal computers, they are used for source control and DC/DC power conversion. In instrumentation equipment, they are used for power supply smoothing and voltage divider circuits. Finally, in LED lamps they can be used as stabilizers for power supply output.

In addition to its wide range of uses, EEU-TA1H220BJ capacitors offer several advantages. Firstly, they provide high capacitance per unit volume, making them suitable for use in small, slim electronic equipment. Secondly, they have very low equivalent series resistance (ESR). This allows them to maintain a stable output voltage even at high frequencies. Lastly, they have lengthy operating lifetimes, typically ranging from 2000-5000 hours.

The working principle of aluminum electrolytic capacitors can be divided into four stages. Firstly, an electric field is created between the positive and negative electrodes. Secondly, ions in the electrolyte diffuse towards the negative electrode. Thirdly, the electrolyte is adsorbed onto the surface of the electrodes, forming an electrical double layer. Lastly, a large voltage is generated in between the electrodes, resulting in a high capacitance.

In conclusion, the EEU-TA1H220BJ aluminum electrolytic capacitor has a high capacitance, low equivalent series resistance, and lengthy operating lifetime, making it suitable for use in personal computers, instrumentation equipment, audio equipment, and LED lamps. Its working principle involves the formation of an electrical double layer between the electrodes by ion diffusion and adsorption on the electrode surface.
