Aluminum electrolytic capacitors, also known as electrolytic capacitors, are passive electronic components used in electronic circuits for storing electric energy, temperature compensation, filtering, resonance, bypass, coupling, and transformer including power supply circuits. MAL203669109E3 is a classic general-purpose aluminum electrolytic capacitor, which is popular and extensively used in the market. This section introduces its application field and working principle.

Application field:

MAL203669109E3 is a highly reliable aluminum electrolytic capacitor with large capacity, low internal resistance and low ESR. It is mainly used in power supplies, electro-optic equipment, communications equipment, precision instruments, military equipment, and automotive equipment. Meanwhile, it can also be used in electrical and power engineering, household appliances, audio equipments, medical equipments and industrial control equipments.

Working principle:

An aluminum electrolytic capacitor consists of two metal plates: an aluminum foil and a metal film. When a voltage is applied, electrons flow into and out of the capacitor, allowing electrical energy to be stored. The capacitance of the capacitor is determined by its area and the distance between the two plates. The higher the capacitance or the lower the distance between the two plates, the higher the capacitance of the capacitor.

When a voltage is applied to an electrolytic capacitor, the electrons will form a micro layer at the surface of the aluminum foil which acts as the dielectric. With the application of current, a reaction will happen and a metal hydroxide will be formed at the surface of the aluminum foil which acts as the other plate of the capacitor. The presence of the metal hydroxide film enables the capacitor to have a high capacitance.

MAL203669109E3 is made of a solid organic electrolyte and has a low dissipation factor, which makes it suitable for high frequency circuits, audio systems, and medical instrumentation. Its construction features high pressure contact and sub-miniature size, which makes it more reliable and safer than other capacitors.

The reliability and electrical characteristics of MAL203669109E3 capacitors depend largely on the quality of the aluminum foil and the insulation materials used. It is recommended to use them under the proper rated voltage and temperature.

In conclusion, MAL203669109E3 is a classic general-purpose aluminum electrolytic capacitor with a wide range of applications. It offers a variety of advantages, such as low internal resistance, low ESR, high pressure contact, and sub-miniature size. With proper care and handling during its installation and usage, it can provide a reliable, safe and efficient performance in any circuit.
