Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrochemical capacitor whose anode electrode is made of aluminum. Aluminum electrolytic capacitors have relatively large capacitors and voltage range, and they are widely used in the fields of electronics such as TVs, radios, computers, mobile phones, VCRs, and audio products. The use of aluminum electrolytic capacitors requires certain knowledge of their working principle and application fields.

Working Principle

The working principle of aluminum electrolytic capacitors is mainly based on the Faraday law of electrolysis. An anode consisting of a thin aluminum foil is processed and rolled into a small cylinder-shaped can and then filled with an electrolyte solution. After connecting a load to the capacitor, an electric field is generated between the anode and cathode electrodes. The electric field produces cations (positively charged particles) on the anode and anions (negatively charged particles) on the cathode. These electrochemical processes combine to form an effective electrical layer on the surface of the anode due to oxidation and absorb the movable negative charges in the electrolyte. The anode is positively charged and will store a certain amount of electricity depending on the applied voltage and the capacitance of the capacitor.

On the other hand, the negative side of the capacitor is generally made of a flat wire which is welded to the bottom of the capacitor shell. Cations are attracted by the negative electrode and gather on the surface of the flat wire, forming an effective insulating layer on the surface of the electrode, thus completing the establishment of the capacitor.

Application Field

The application field of MAL201351479E3 is mainly in the low-frequency and small electric power devices. The general capacitor voltage is between 16V - 450V and capacitance is about 47uF - 20000uF. The special specification models are also available. It is mainly applied in motor electronic speed control, electrical equipment, aerospace technology, and special electronic equipment.

Besides, this aluminum electrolytic capacitor is also suitable for general circuits, especially in the circuit with large ripple current. The reason for this is because of the high withstand voltage, large capacity, low equivalent series resistance (ESR), long life, and high performance of the aluminum electrolytic capacitor.

At the same time, aluminum electrolytic capacitors also have certain drawbacks in their application fields. The anode of aluminum foil, due to its low plasticity, the capacitor formed has a large size, and the volume ratio of the capacitor is not high. Moreover, the performance of the electrolytic capacitor depends on the rationality and quality of the production process. Generally, the accuracy of the actual capacitance is relatively low, and the temperature coefficient of the capacitance is relatively large, so the reliability of the capacitor is affected.

Conclusion

In conclusion, the aluminum electrolytic capacitor MAL201351479E3 has wide applications in various electric and electronic products. It’s a useful electronic component in its application fields – motor electronic speed control, electrical equipment, aerospace technology, and special electronic equipment – due to its high withstand voltage, large capacity, low equivalent series resistance, and good performance. However, it also has certain drawbacks like low accuracy of the actual capacitance and large temperature coefficient of the capacitance, and these drawbacks should be taken into consideration when applying in electrical and electronic products.
