The MAL213668121E3 aluminum electrolytic capacitor has a wide range of applications and performs well in a variety of scenarios. In this article, we will take a look at the application scope and working principle of MAL213668121E3 aluminum electrolytic capacitor.

Application Scope of MAL213668121E3 Aluminum Electrolytic Capacitors

The MAL213668121E3 aluminum electrolytic capacitor is a surface-mount aluminum electrolytic capacitor that is highly compatible with various application scenarios. Due to the characteristics of high capacitance, high stability, high reliability, and wide operating temperature range, it is widely used in a variety of power supply, inverter, and switching power supply circuits, and is also widely used in laptops, LCD TVs, industrial production, audio devices, mobile phones, LED driver circuits, lighting, etc. In the low temperature impact test (which is used to simulate conditions such as cold storage, low temperature transport environment, etc.), the MAL213668121E3 aluminum electrolytic capacitors have demonstrated excellent performance. The MAL213668121E3 aluminum electrolytic capacitors are also used in the ignition system of gasoline engines and for spark plug capacitors, in addition to providing energy storage for car alarms, radios, etc.

Working Principle of MAL213668121E3 Aluminum Electrolytic Capacitors

The structure of MAL213668121E3 aluminum electrolytic capacitors is made of a layer of aluminum foil as the anode electrode, which is rolled into a cylinder and filled with electrolyte to form the anode. The electrolyte is not easily penetrated by the external air and has a small leakage current, so it has good electrical properties. And a layer of aluminum oxide film formed on the surface of the anode electrode acts as the dielectric. Conversely, a layer of metal as the cathode electrode is bonded to the outside of the aluminum oxide layer.

The MAL213668121E3 aluminum electrolytic capacitor works in the same way as a basic capacitor. The two electrodes (the anode and the cathode) are separated by an isolating material (the dielectric) which is the aluminum oxide layer formed on the surface of the aluminum foil of the anode electrode. When a voltage is applied to the aluminum electrolytic capacitor, the anode and cathode electrodes create an electric field. The current generated by the electric field charges the capacitor by depositing positive and negative charges on the anode and cathode respectively. This electric field stores the energy in the MAL213668121E3 aluminum electrolytic capacitor.

Conclusion

MAL213668121E3 aluminum electrolytic capacitors are widely used in a variety of electronic products. Their excellent performance is due to the aluminum foil as the anode electrode and aluminum oxide layer as the dielectric material. When a voltage is applied, current generated by the electric field charges the capacitor by depositing positive and negative charges on the anode and cathode respectively. Through these properties, MAL213668121E3 aluminum electrolytic capacitors provide excellent performance in a variety of situations and are widely used in power supply, inverter, and switching power supply circuits, and laptops, LCD TVs, industrial production, audio devices, mobile phones, LED driver circuits, and automotive electronics.
