Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are divided into two categories: polar electrolytic capacitors and non-polar electrolytic capacitors. Polar aluminum electrolytic capacitors are the most common type of aluminum electrolytic capacitors, and their capacitance is among the largest, measuring up to thousands or even tens of thousands of microfarads. The non-polar aluminum electrolytic capacitors are generally small in size and have a relatively small voltage. Polar and non-polar aluminum electrolytic capacitors are both similar in construction, with a layer of aluminum oxide film continuously fixed to the capacitor body as a dielectric.EEV-TG1E221UP aluminum electrolytic capacitors belong to the polar aluminum electrolytic capacitor. Its capacitance is 220μF and its working voltage is (25 ± 20%)50V. It has huge energy storage because of its large capacitance and large voltage. The main components of the EEV-TG1E221UP aluminum electrolytic capacitor are three electrodes, an insulating lining, a welding staff and an outer casing, where the two outer electrodes are respectively connected to aluminum foil and a dielectric is constructed inside.The insulation of the EEV-TG1E221UP aluminum electrolytic capacitor can be seen from two aspects. On the one hand, the insulating lining is wrapped around between electrodes, which can effectively prevent contact between electrodes. On the other hand, during the manufacturing process of aluminum electrolytic capacitors, an anhydrous aluminum oxide thin film is formed on the surface of the aluminum foil at a high temperature, which has a good insulation effect. In addition, in the vicinity of the metal material, there is an insulating film with a molecular structure that can shield metal ions from entering the outside.The working principle of the EEV-TG1E221UP aluminum electrolytic capacitor is the same as other aluminum electrolytic capacitors in general. When an external voltage is applied, a potential difference is generated between the two electrodes, which causes electrons to move to the negative electrode, resulting in an accumulation of negative charges. At the same time, the positive charges are drawn to the positive electrode, resulting in an accumulation of positive charges and the capacitor entering a full charged state. When the alternating current flows through the external circuit to the EEV-TG1E221UP aluminum electrolytic capacitor, the current flows through the capacitor in the form of alternating current, and the charge on the plate of the capacitor changes periodically. Between the two electrodes, different potentials are generated according to the change of charge, so that the current in the external circuit is also changed. This phenomenon is what is called capacitance effect.Due to its large capacitance and large voltage, the EEV-TG1E221UP aluminum electrolytic capacitor is mainly used in voltage stabilization, filtering, and power frequency storage. It is commonly used in industrial fields such as computers, communications, intelligent home appliances, automotive electronics and consumer electronics, and plays a critical role in improving product power saving efficiency. In the following applications, care should be taken to ensure that the rated voltage does not exceed the voltage of the EEV-TG1E221UP aluminum electrolytic capacitor:1. It can be used as energy storage and voltage stabilization filter in switching power supply;2. It can be used as charging voltage in battery.3. It can be used as frequency synthesizer filter of frequency stabilizing system in cellular phone communication system.4. Used in general charging, high-frequency selectivity, buffer and active filter circuits.5. It can also be used in compensating for harmonic currents in rectifier circuits.When using the EEV-TG1E221UP aluminum electrolytic capacitor, it is important not to exceed the rated voltage, as the capacitor will be easily damaged if the voltage exceeds the rated voltage. It is also important to note that the temperature of aluminum electrolytic capacitors needs to be kept below its rated temperature, as both dielectric and variety lead can be prone to thermal decomposition due to excessive temperature. It is not recommended to use an aluminum electrolytic capacitor after a long period of storage, and instead it is advised to purchase a new capacitor to prevent performance inconsistencies and failure.
