Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are widely used in electronic devices due to their superior properties such as high energy density, long life and reliable performance. They are typically constructed of two aluminum metal foils separated by an electrolyte. The anode is formed by the aluminum metal foil and the cathode is formed by the electrolyte. AECs are alternately referred to as electrolytic capacitors or electrolyte capacitors. There are many types of AECs for a variety of applications.

SLP181M350A7P3 is an AEC with low resistance, low equivalent series resistance and high ripple current of 350A, making it ideal for high-end applications. The main features of the SLP181M350A7P3 include a high temperature range of -55 to +125°C, a capacitance rating of 181μF, a rated voltage of 350Vdc, and a rated temperature of 105°C.

Application Field

SLP181M350A7P3 AECs are widely used in automotive, solar power, military, medical, consumer electronics, and instrumentation applications. Due to their good heat dissipation, they are often used in high power converters, dc/dc converters, and high voltage inverters. SLP181M350A7P3 AECs are also frequently used in resonant circuits, such as in power supply filters, and as energy storage elements in power supplies and inverters.

Working Principle

The working principle of SLP181M350A7P3 AECs is based on the so-called “double layer” effect. This effect occurs when the capacitor is chemically treated with an electrolyte solution and two metal sheets, separated by the electrolyte solution, are used as the two electrodes. As an electric current is applied to the metal sheets, a dielectric layer is formed between the two metal sheets, and this dielectric layer stores electric charge.

The ability of SLP181M350A7P3 AECs to store charge is dependent upon the ratio of the distance between the two metal sheets and the dielectric layer thickness. The capacitance of the AECs is proportional to the ratio and is inversely proportional to the frequency of the applied electric current. Additionally, the higher the temperature of the electrolyte solution, the lower the capacitance of the AECs

Conclusion

In conclusion, Aluminum electrolytic capacitors, especially the SLP181M350A7P3 model, are used in a variety of applications due to their high energy density and reliable performance. Their working principle is based on the “double layer” effect, which increases the capacitance of the AECs when an electric current is applied to the metal sheets that are separated by the electrolyte solution. This makes them ideal for high-end applications like dc/dc converters and high voltage inverters.
