Aluminum electrolytic capacitors are a kind of components widely used in power electronic products. They are made of a thin aluminum oxide film as the dielectric, a specially processed aluminum foil as the anode, and an electrolyte as the cathode. The MAL205972102E3 is a particular type of electrolytic capacitor that has a reliable performance with an 85°C operating temperature and 2000 hours life.The main purpose of the MAL205972102E3 is used to filter out noise frequency and low frequency ripple of different power electronic systems. It is mainly used in applications such as frequency conversion, power inverters, switching power supplies, and motor drives. Its advantages include low equivalent series resistance (ESR), low equivalent series inductance (ESL) and high capacitance.The working principle of the MAL205972102E3 starts with the structure. It consists of two aluminum foils separated by a dielectric layer, usually an aluminum oxide.The foil acts as two capacitors and one works as a positive electrode while the other works as a negative electrode. When a DC voltage is applied, a charge accumulates on one side, while the opposite side remains at a negative voltage, generating a capacitive effect.The size of the MAL205972102E3 is not very large, but its capacity is relatively large. The capacitance of the aluminum electrolytic capacitor is mainly related to the area of the semiconductor oxide film and the thickness of the oxide film. The capacitance is calculated according to the following formula: C=ε·S/d, where ε is the dielectric constant of the dielectric medium, S is the electrode area, and d is the dielectric layer thickness.The other technology related to the MAL205972102E3 is the capacitors ESR. ESR is the abbreviation of equivalent series resistance, mainly related to the structure of aluminum electrolytic capacitor. The inside of the MAL205972102E3 is a cylindrical structure. The complex internal structure will cause ohmic losses and lead to ESR of capacitor. It is generally agreed that the ESR of MAL205972102E3 is very low, that is, several milliohms.Finally, the current leakage and dielectric loss of the MAL205972102E3 are also important factors. Due to the large capacity of MAL205972102E3, if the traditional design is still adopted, when the capacitor is charged at a high rate or the output current is too large, the leakage current and dielectric loss occur in the capacitor. The leakage current will increase with the increase of the working temperature. If we want to make the capacitor more stable, we need to ensure both the leakage and dielectric loss are within a safe range.In a word, MAL205972102E3 is a kind of aluminum electrolytic capacitors with high reliability and large capacity. It is suitable for high power applications such as frequency conversion, power inverters, switching power supplies and motor drives. Its advantages include low equivalent series resistance, low equivalent series reactance and high capacitance. Therefore, it has a wide range of applications.
