Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors, or AECs, are one of the most widely used components in electronics. They are popular due to their relatively small size and low cost, and their ability to store very large amounts of energy. AECs are indicators of electrical current which are found in nearly all types of electronic applications. They are used extensively in consumer, automotive, industrial, military, and medical applications.

MAL20386622E3

MAL20386622E3 is a type of Aluminum Electrolytic Capacitor, designed to offer superior energy storage at an affordable price. Its core components are an aluminum case, an anode and a cathode which are connected by a non-solid electrolyte. The shape of the component is cylindrical, with height and width varying depending on its capacity. The body is equipped with a mounting pole that facilitates quick mounting on Printed Circuit Boards.

Application Field

MAL20386622E3 Aluminum Electrolytic Capacitors are suitable for applications that require large currents, such as converters, motor drives, relays, generators, UPS systems, and high fidelity audio systems. In these applications, AECs require a certain amount of energy storage to be effective. This is known as their "working field", and the MAL20386622E3 has a working field of 2.2v-35v, which can provide a very wide range of voltage levels.

Working Principle

The working principle of MAL20386622E3 Aluminum Electrolytic Capacitors is relatively simple. Electricity flows in the component through the anode and cathode, creating a potential difference. This potential difference is stored in an electric field, allowing current to remain, even in the absence of a power source. As current is cycled through the anode and cathode, stored electrical charge bleeds away slowly, which causes the capacitor to lose its charge gradually over time.

When current is applied to the capacitor, electric charge builds up on the anode and cathode. As the voltage level of the capacitor reaches the upper working voltage, the stored charge begins to leak from the capacitor. This is known as "bleed current". The amount of current lost depends on the capacitance of the component and the voltage level that is applied, with higher capacitance usually associated with a higher bleed current.

The capacitance of an AEC is determined by several factors, including the size of the anode and cathode, the electrolyte used, and the dielectric value of the material. An important parameter in evaluating the performance of any capacitor is its equivalent series resistance (ESR), which is a measure of the material\'s resistance to current flow. AECs typically have very low ESR levels, meaning they are extremely efficient in their ability to store electrical energy.

Conclusion

MAL20386622E3 Aluminum Electrolytic Capacitors are highly suitable for electronic applications that require high levels of energy storage. These components are relatively inexpensive, and can be easily mounted onto printed circuit boards. They have low ESR levels and can handle a wide range of voltages, making them a very reliable and cost-effective choice for many different applications.
